Question

What is the solution to this equation? 4(5x + 3) = 14x + 30 A. x = –7 B. x = –3 C. x = 3 D. x = 7

Answer 1

Answer:

C (x=3)

Step-by-step explanation:

4(5x+3)=14x+30

1) Use the Distributive property on the left side of the equation:

20x+12=14x+30

2) Subtract a 12 from both sides:

20x=14x+18

3) Subtract a 14x from both sides:

6x=18

4) Divide both sides by 6:

x=18/6

5) Simplify the fraction 18/6:

x=3
