Question

Please need some help on this

Answer 1

All you have to do is simplify the equation, and then isolate g.

-5 + 7g = 3g + 9                       add 5 to both sides to isolate 7g

7g = 3g + 14                             subtract 3g from both sides to isolate g

4g = 14                                     divide both sides by 4 to isolate g

g = 3.5

The answer is D- 3$\frac{1}{2}$

Answer 2

This is the work. the answer is g=1.4
