SOLVING MULTI-STEP EQUATIONS
USING THE DISTRIBUTIVE
PROPERTY
2.3 B
OBJECTIVE

TSWBAT solve multi-step equations using the
distributive property.
VOCABULARY

Distributive Property
Solve each equation.
-4x + 3(2x – 5) = 31
-4x + 3•2x – 3•5 = 31
1. Distribute to undo the
parenthesis
-4x + 6x – 15 = 31
2. Combine like terms on the
same side of the equal
sign.
2x – 15 = 31
+ 15 +15
3. Undo the number being
add/sub. to the variable.
2x = 46

4. Undo the number being
multiplied/divided to the
variable.
x = 23
Solve each equation.
1. 6(t + 5) = -36
3. - (b – 5) = 10
2. 7 - 2(x + 1) = 8
4. -w + 4(w + 3) = -12
Find the value of x.
1.
2x + 12
3x
2x – 12
2.
