Question

what do 2(3g+2)=1/2(12g+8)

Answer 1

clear the brackets and move the variable to one side

Answer 2

Evaluate 2(3g+2). That would be 6g+4 (when you use the distributive property).
Evaluate 1/2(12g+8). Remember that you are finding half/0.5 of 12g and 8. That will be 6g+4.
The evaluation of both of these are 6g+4=6g+4.

Answer 3

same issue as the last one g=g
g = all real numbers, can't solve for an exact value
