Answer:
38 is your answer :)
Step-by-step explanation:
So what you want to do is P.E.M.D.A.S (parenthesis, exponets, multiplication/division, addition/subtraction) * whatever comes first always do it in order*
3^2+12/ (6-3) x 8
6-3 = 3
3^2+12/(3)*8
3^2+4*8
6+4*8 =32 and 32+6 = 38
C = 5(F-32)/9 Multiply each side by 9
9C = 5(F-32) Distribute
9C = 5F - 160 Add 160 to each side
9C + 160 = 5F Divide each side by 5
9/5C + 32 = F

X+2y=12
X+2y=12-12
X+2y-12=0
