Solving Equations with Variables on Both Sides

What is the first step in solving equations with variables on both sides?

• Divide by the coefficient of the variable

• Add or subtract constants

• Look for distributive property

• Combine like terms

In the first example, what operation is performed to move -8x to the other side?

• Divide both sides by 8

• Subtract 8x from both sides

• Multiply both sides by 8

• Add 8x to both sides
