Solve for y:
2x + 2y = 6

• y = - x + 3

• y = x + 3

• y = 2x +6

• y = - 2x + 6

Which of the following is equivalent to 4x - 3y = 15?

Solve -7x + 7y = 21 for y

• y = 3x + 3

• y = -3x + 3

• y = x + 3

• y = x - 3

-4=-x+2y 

•  x-2y=4

• x-2y=-4 

• 4=x-2y 

• x+2y=4 

The amounts that two plumbers charge for their services are described.

* The first plumber charges a fixed fee of $40 for the house calls and $15 per hour of work.

*The second plumber charges a fixed fee of $30 for house calls and $19 per hour of work.

For what number of hours of work do the first plumber and the second plumber charges the same total amount?

Rewrite the equation in STANDARD form.

-16x=2y-10

• 8x+y=5

• -16x-2y=10

• 16x+2y=-10

• 8x-y=-5
