Solving One-Step Equations

Solve for z in the following equation:

z - 33 = 147

• z = 114

• z = 177

• z = 180

• no solution

SOLVE 10=z+6

8y = 48

• 36

• -36

• 4

• -4

q - 12 = 1

Solve for h in the following equation:

0 = 4h

• h = 4

• h = 1

• h = -4

• h = 0

Solve for x in the following equation:

20.5 = x + 4

• 16.5

• 16.05

• 24.5

• 24.05

In the equation

x + 7 = 12

7 is being added to the variable, x.

How should you show your work to isolate the variable and solve the equation?

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.

  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.

The inverse operation of addition is ??????????

• addition

• subtraction

• multiplication

• division
