Solving Multi-Step Equations with Distribution

The video tutorial explains how to solve a multi-step equation. It begins by introducing the concept of equations being equal on both sides and the need to distribute numbers next to parentheses. The process involves distributing, rewriting the equation, isolating the variable, and using inverse operations to eliminate constants. Finally, the equation is solved by dividing both sides, resulting in the solution for the variable.

What does it mean when an equation is equal on both sides?

• Both sides have the same value.

• Both sides have the same number of terms.

• Both sides have the same coefficients.

• Both sides have the same variables.
