Question

−15 = 5(3q − 10) − 5q

Answer 1

Answer:

q = 3.5

Step-by-step explanation:

-15 = 5(3q - 10) - 5q

-15 = (5*3q + 5*-10) - 5q

-15 = 15q - 50 - 5q

-15 + 50 = 15q - 5q

35 = 10q

q = 35/10

q = 3.5

Check:

-15 = 5(3*3.5 - 10) - 5*3.5

-15 = 5(10.5 - 10) - 17.5

-15 = 5*0.5 - 17.5

-15 = 2.5 - 17.5

Answer 2

Answer: q= 3.5

Step-by-step explanation:

1. Apply the distributive property= -15 = 15q +-50-5q

2. Combine like terms= -15 = 10q +50

3. Add 50 to both sides= 35 = 10q

4. Divide both sides by 10

q= 3.5
