Sally bought three candy bars for a total of $18.00. How much did each candy bar cost? Write an equation to solve this problem. Use c as your variable.

• 18c=6

• c + 6= 18

• c +18 = 6

• 3c=18

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

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.

n - 4 = 12

• 12

• -48

• 8
