Explain why it is important to perform the same operation on both sides of an equation.

Performing the same operation on both sides ensures that the equation remains balanced and the equality is maintained.

Solving Multistep Equations

7th Grade•60 minutes

I can solve multi-step equations with variables on both sides.

When solving equations with variables on both sides, the goal is to isolate the variable on one side of the equation.

To isolate the variable, perform the same operations on both sides of the equation to maintain equality.

In the equation 2x + 3 = 5x - 2, we can subtract 2x from both sides, then add 2 to both sides to begin isolating the variable.
