Solve and check: -10z = 40

• z = 50

• z = 30

• z = -4

• z = 4

Solve and check: x/2 = -10

• x = 20

• x = -20

• x = 5

• x = -5

What is the first step to solve this equation:

 $11-3x=44$  

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.
