Equation One Variable

If 5(x – 6) = 2(x – 3) then the value of x + 3 is ....

• 8

• 11

• 7

• -9

If 3(y + 2) + 5 = 2(y + 15), then the value of y - 2 = ....

• 23

• 21

• 17

• 15

Solve for p:
3(p + 2) = -3(p + 2)

• p = -2

• p = 2

• p = 3

• p = -3

The equation below which includes a one-variable linear equation is ....

• x  + 2y = 14

• –x + 2y = 14x

• 3 + 2x = 10

• x – 3y = 31

Solve x/2+1/3=-5/3

• x=4

• x=2

• x=-4

• x=-2
