Harris · Answer 1

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
