Add 4G to each side
9G = 45
Divide each side by 9
G = 5
X^2-7x+38=5x+3
x^2-7x+38-5x-3=5x+3-5x-3
x^2-12x+35=0
Factoring:
(x-5)(x-7)=0
Two solutions:
x-5=0→x-5+5=0+5→x=5
x-7=0→x-7+7=0+7→x=7
Answer: x=5 and x=7
Answer: Options B. 7 and D. 5
You don't switch it unless for example 7<x the X has to be on the other side X>7
Oof that a weird question the answer is 36 blocks
