Solve for the variable
-8g-13=43 add 13 to both sides
-8g=56 divide both sides by -8
g=-7
84-x=27 subtract 84 from both sides
-x=-57 multiply both sides by -1
x=57

What you want to do here is plug 2 in for x. when a question asks you to evaluate a certain equation at a certain number, it's just asking you to plug the value in for your variable. i'm assuming that 12x + 8 is meant to be set over 4 as a fraction.
(12(2) + 8)/4 ... figure out the top first. 12*2 = 24, 24 + 8 = 32.
32/4 = 8, so your correct choice is D.
