Answer:

g=10

Explanation:

Add 1.5 to both sides and cancel out the -1.5 on the left side. Then you'll have -0.5g=-5

Then you divide by -0.5 and isolate the variable, which means that the g will be by itself, and -5 divided by -0.5 is equal to 10.

So g=10

-0.5g-1.5=-6.5

We move all terms to the left:

-0.5g-1.5-(-6.5)=0

We add all the numbers together, and all the variables

-0.5g+5=0

We move all terms containing g to the left, all other terms to the right

-0.5g=-5

g=-5/-0.5

g=+10
