Jason has $90 to spend. He wants to purchase a bad for $30, one eraser for $10, and 3 pencils. Each of the pencils costs the same price. This will use up all of Jason's money. Determine the equation for this situation.

• 90 = 30 + 10 + 3

• 90 = 31 + 3p

• 90 = 40 + 3p

• 90 = 43p

Solve: 3/6x + 6 = 12

• x = 3

• x = 6

• x = 12

• x = 24

5/7x - 14 = -22

• x = 8

• x = 11.2

• x = -8

• x = -11.2
