Math 8 Solving Equations Test

Solve for p:

7p + 4p = -2(p-2) + 5(5p + 4)

• p = -2

• p = 14

• p = 13

• p = -12

Solve for a:

-19 = -8(-4 + a) - 2a - 1

• a = -1

• a = 14

• a = -5

• a = 5

If I solved an equation and my answer ends up with 5 = -3, what is my solution?

• one solution

• no solution

• many solutions

• none of these

In order to solve an equation, we must get get variables on one side of an equation, and constants on the opposite side.

• True

• False

Solve for b:

-11 + 3(b + 5) = 7

Solve for x:

2x - 3 + 4x = 27

What operation would you perform first and second when solving for m in the following equation:

10 + 7m = 17

• subtract 10, divide by 7

• divide by 7, subtract 10

• multiply by 7, add 10

• add 10, multiply by 7

What is the first step you you would perform to solve the following equation?

-3x - 11 = 44

• add 3

• subtract 11

• add 11

• divide by 3

What is the inverse of addition?

• addition

• multiplication

• subraction

• division

What is the goal when solving algebraic equations?

• get the answer
