-n/3=4
-n/3 x 3=4 x 3
-n=12
-n/-1=12/-1
n=-12
I did my math on a piece of paper but the answer would be x= 107/96
4(x-3)-(2x+5)=-3x-27
4*x - 4*3 - 2x - 5 = -3x - 27
4x - 12 - 2x - 5 = -3x - 27
2x - 17 = -3x - 27
2x + 3x = -27 + 17
5x = -10 / : 5
x = -2
Find out what number goes into 8 and 10 then figure out how many times that number goes into 100
