-6x+72=x then -7x=-72 so x=72/7
54(x)+52+32(y)+72=212
You would formulate this problem X/100 * 150 = 72 and solve for X.
(x-9)(X+8)
42 72
6x + 10 = 72 6x = 72 - 10 x = 62/6 x = 10.3333
U = 4 x 18 U = 72
y=84-72=12 z=84-52=32 x=84-12-32=40
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
it equals 72. just do 12 X 6
(x + 12)(x - 6) = 0 x = 6 or -12
By putting a slash through the equals sign, 8 x 8 ≠72.
