What is the inverse operation needed to solve the following one-step equation?
450 = p - 345

• subtraction

• addition

• multiplication

• division

• Subtract 11 on both sides, y=11

• Add 11 on both sides, y=11

• Add 11 on both sides, y=33

• Add 11 on both sides, y=22

• Divide by 14 on both sides, h=7/14

• Multiply by 7 on both sides, h=98

• Multiply by 14 on both sides, h=98

• Divide by 7 on both sides, h=2

• Subtract 4 on both sides, y=6

• Subtract 10 on both sides, y=-6

• Add 4 on both sides, y=14

• Add 10 on both sides, y=4
