Multi-Step EquationsNotes and Practice

Essential Question

How do I solve an equation that has more than one variable term?

Multi-Step Equations

Equations will not always be able to be solved in one or two steps.

You will see many more complicated equations in higher math.

6 – x – 3 = 4(x – 2) + 4

Process

Simplify both sides of the equation separately

Add/subtract to get all variable terms to one side of the equation (stay fair and balanced!)

Get the variable alone

Example

2x – 5(x + 4) = -2

Example

1443 xx

Practice

1) 5y – 7 = 3y – 13 2) 4(w + 1) – 2 = 18

3) 7x + 3 – 12 = -x + 7 4) 3(x – 2) = 12

5) 2x + 4 + 3x = 20 + x + 8 6) 9p + 27 – 3p = 72

What about that original problem?

6 – x – 3 = 4(x – 2) + 4
