Ch2L5-Solve Multi-Step Equations Practice

Question 1

Multiple-Step Functions: some equations contain expression with grouping symbols. examples like:

15(20+d) = 420

Answer 1

To solve these,

first expand the expression using Distributive Property. Then Collect like terms if needec.

Then solve the equation using Property of Equality.

Step 1: 15X20 +15d = 420

Step 2: 300 + 15d - 300 = 420 -300

Step 3: 15d/15 = 120/15

solution: d = 8

Question 2

6(x-3)+10 = 2(3x-4)

Question 3

8(4-2x) = 4(3-5x) + 4x

Question 4

3(6-4x) = -2(6x-9)

Question 5

2(3x+5) = 5(2x-4)-4x

Question 6

At the fair, Hunter bought 3 snacks and 10 ride tickets. Each ride ticket costs $1.50 less than a snack. If he spent a total of $24, what was the cost of each snack?

Question 7

-8(w-6) = 32

Question 8

8(3a+6) = 9(2a-4)
