What value of Y makes the equation true ?

What Value Of Y Makes The Equation True ?

Answers

Answer 1

Answer:

y = -5/2 or -2.5

Step-by-step explanation:

3y + 4 = -y - 6

add y to both sides

4y + 4 = -6

subtract 4 from both sides

4y + 4 - 4 = - 6 - 4

4y = -6 - 4

4y = -10

divide both sides by 4

4y/4 = -10/4

y = -10/4

y = -5/2 or -2.5

Answers

x = 1.6

f = 0.5

0.5(x) = 8x -12

0.5x= 8x -12

subtract 8x from both sides

-7.5x = -12x

Divide by -7.5x, both sides

X=1.6
