Solving One-Step AND Two-Step Equations

Solving Equations

100

Use a vertical line starting at the = to separate the 2 sides of the equation

What is the 1st step needed to solve equations?

200

Isolate the variable, so the unknown is on one side of the equal sign and everything else is on the other side.

What is the goal when solving all equations?

300

Use inverse operations to remove all Additions and Subtractions that are on the same side as the variable

What are the first steps in isolating the variable?

400

Use inverse operations to remove all multiplications and divisions that are on the same side as the variable.

What are the 2nd step(s) to isolate the variable?

500

The reverse of PEMDAS

What is the order for solving equations
