Step-by-step explanation:

4x – 2y = -8
y = 2x + 4

Answers

Answer:

Set any x and then compute y as 2x + 4. The pair solves the equations.

Step-by-step explanation:

4x - 2y = -8

4x = 2y - 8

2x = y - 4

y = 2x + 4

2x + 4 = y

2x = y - 4

Both equations are the same, so any pair of x and y for which 2x = y - 4 works.

Set any y and then compute x as (y - 4)/2

Alternatively

2x = y - 4

2x + 4 = y

Set any x and then compute y as 2x + 4.

Washer and a dryer cost $746 combined washer cost $96 more than the dryer what is the cost of the dryer

Answers

Answer:

$325

Step-by-step explanation:

Given data

let the cost of dryer be x

let the cost of wahser be y

so

x+y= 746--------------1

y= x+96----------------2

put y=  x+96 in equation 1

x+ x+96= 746

2x+96= 746

2x= 746-96

2x=650

divide both sides by 2

x= 650/2

x=325

Hence the cost of the dryer is $325

Answer:

I think it´s D

help what do i do i need help asap

Answers

I am assuming your teacher wants you to solve for v.

Therefore we need to isolate v, first step will be moving 2 to the other side then multiplying both sides by 11.

4=v/11-2

4+2=v/11

6=v/11

6*11=v/11*11

66=v

v=66

Check answers: substitute v=66 back into the equation.

right hand side:66/11-2=6-2=4

left hand side:4

RHS=LHS therefore the solution is correct.

Done!

Hope this helped, if there are any questions just ask them in the comments and I will answer them.

Answer:

66 = v

Step-by-step explanation:

4 = v/11 -2

+2 +2

6 = v/11

*11 *11

66 = v
