SOLVING TWO-STEP EQUATIONS Section 7.5

A two step equation is an equation that involves two operations. –Goal is to get the variable to stand alone –Get rid of tails first by adding or subtracting (watch your signs) –Last, multiply or divide

EXAMPLE 1 3X – 2 = = +2 3X = X = 2 1. Identify your variable 2. Identify your tails 3. Use inverse operations to get rid of your tails. 4. Do the math 5. Determine what you need to do to get your variable to stand alone. 6. Use inverse operations 7. Do the math

Solving Two-step Equations Identify your variable Identify your tails Use inverse operations to get “rid” of your tails (addition or subtraction) Determine what you need to do to get your variable to stand alone. Use inverse operations to get your variable alone (multiplication or division) Do the math
