What is the inverse operation needed to solve for p?
765 = p - 254

• subtraction
• addition
• multiplication
• division

how would you solve this equation: 9x=153? 

• multiply
• divide
• add
• subtract

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.

x - 62 = 123

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

• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.
