Which of the following equations has the solution x = 5? a. 2x + 9 = 15 b. 3x + 7 = 22 c. 2x – 5 = 17 d. 3x – 6 = 15

B. 3x+7=22

Step-by-step explanation:

Lets solve each equation alone to find the possible solutions.

A. 2x+9=15

Putting like terms together.

2x=15-9

2x=6

x=3

B. 3x+7=22

Collecting like terms together:

3x=22-7

3x=15

x=5

C. 2x-5=17

2x=17+5

2x=22

x=11

D. 3x-6=15

3x=15+6

3x=21

x=7.

The only equation that gives x=5 is B. 3x+7 =22

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
