9=3x-y
6x=3y+3
Answer:
x = 8; y = 15
Step-by-step explanation:
First choose any one equation and isolate a variable of your choice
I will use the first equation and isolate variable y
9 = 3x - y
Add y to both sides to make it positive
y + 9 = 3x - y + y
Subtract both sides by 9 to isolate the variable y
y + 9 - 9 = 3y - 9
y = 3x - 9
Now that we know what expression is equal to y, we can substitute this value of y into the second equation
6x = 3(3x - 9) + 3
Use distributive property
6x = 9x - 27 + 3
Combine like terms
6x = 9x - 24
Subtract both sides by 9x
6x - 9x = 9x - 9x - 24
-3x = -24
Divide both sides by -3 to isolate the variable x
-3x ÷ -3 = -24 ÷ -3
x = 8
Plug this value of x into either equation
I will use the first equation because it is shorter
9 = 3(8) - y
9 = 24 - y
Add y to both sides to make y positive
y + 9 = 24 - y + y
y + 9 = 24
Subtract 9 from both sides to isolate the variable y
y + 9 - 9 = 24 - 9
y = 15
-7x + y = -19
-2x + 3y = -19
solve for x and y using elimination
Answer:
x = 2, y = -5
Step-by-step explanation:
[tex]-7x + y = - 19 --> -21x + 3y = -57[/tex]
[tex]\left \{ {{-21x+3y=-57} \atop {-2x+3y=-19}} \right.[/tex]
subtract
[tex]-19x = -38\\x= 2[/tex]
substitute
[tex]-2*2 + 3y = -19\\-4 + 3y = -19\\3y = -15\\y = -5[/tex]

Step-by-step explanation:
to find the scale factor you take the coordinates of the image and divide it by the coordinates of the preimage
ex. A' coordinates are (3,1)
A coordinates are (6,2)
3/6=1/2
1/2=1/2
therefore the scale factor is 1/2

23 beause the shade links of the garden
Answer:
Step-by-step explanation:
Each side of the square garden is 3 inches. Convert each side to sq ft. 1 1/2 x2 = 3 inches. So 4ft x 2 =8ft. 8ft. X 4 sides = 32ft perimeter that needs coverage. Each link equals 2.67 or 2 2/3. 12x2.67=32.04

Solution??
Answer:
x=−3/4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
435=−4x+285
Step 2: Flip the equation.
−4x+285=435
Step 3: Subtract 28/5 from both sides.
−4x+285−285=435−285
−4x=3
Step 4: Divide both sides by -4.
−4x−4=3−4
x=−34
Answer:
as a decimal: [tex]x=-0.75[/tex]
as a fraction: [tex]x=-\frac{3}{4}[/tex]
Step-by-step explanation:
note: i'm going to convert the fractions to decimals because i prefer working with decimals rather than fractions :)
[tex]8\frac{3}{5}[/tex] as a decimal is [tex]8.6[/tex][tex]5\frac{3}{5}[/tex] as a decimal is [tex]5.6[/tex]the equation is now [tex]8.6=-4x+5.6[/tex]first, subtract 5.6 from both sides of the equation.
[tex]5.6[/tex] and [tex]-5.6[/tex] cancel each other out, leaving you with [tex]-4x+0[/tex] on the right side of the equation. it's not necessary to leave the [tex]0[/tex] in the equation, so just leave it as [tex]8.6=-4x[/tex]now subtract [tex]5.6[/tex] from the left side of the equation. [tex]8.6-5.6=3[/tex], therefore the equation is now [tex]3=-4x[/tex]then divide both sides of the equation by -4.
you are left with [tex]x[/tex] on the right side of the equation and [tex]-\frac{3}{4}[/tex] or [tex]-0.75[/tex] on the left side of the equation, aka [tex]x=-0.75[/tex] or [tex]x=-\frac{3}{4}[/tex]and that's it! the solution as a fraction is [tex]x=-\frac{3}{4}[/tex] and as a decimal is [tex]x=-0.75[/tex].
if you want to check the solution, just plug one of those values in for [tex]x[/tex] in the original equation. since i converted it all to decimals, i'll check my answer using [tex]-0.75[/tex] for [tex]x[/tex] in [tex]8.6=-4x+5.6[/tex].
first, plug in -0.75 for x.
[tex]8.6=-4x+5.6[/tex] ⇒ [tex]8.6=-4(-0.75)+5.6[/tex]begin simplifying by multiplying -4 and -0.75.
[tex]-4(-0.75) = 3[/tex][tex]8.6=3+5.6[/tex]add 3 and 5.6.
[tex]3+5.6=8.6[/tex][tex]8.6=8.6[/tex]since both sides of the equation are equal, that means your [tex]x[/tex] value is correct and therefore a solution to the equation!! :)
i hope this helped! have a lovely rest of your day <3
