Solving 2 step equations

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

Solve 2x - 3 = 1

• 3

• 2

• 1

• -2

Solve 3x - 7 = 32

• 13

• 3

• 12

• 7

33 = 4a - 7

• a=-10

• a=10

• a=4.5

x - 62 = 123

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

• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.
