(3x*x+3x*x+x*x)*2=120,
(32-2x)x=120 (x+3)^2=-x(x+5) 两个方程
x-x/4-120=x/2
60+3x=120+2x x=?
2X+X+2x+5/3=120
计算x-2/5x+120=3/4x
怎么算x 2x 3x=120
怎么算x+2x+3x=120
120/x=120/(X-2)-3
x+2/3x=60 x-3/5x=120 4x+18x=1x+2/3x=60 x-3/5x=120 4x+18x=132!
x+3分之2 x=60 x-5分之3x=120 4x+18x=132x+3分之2 x=60 x-5分之3x=120 4x+18x=132
X+3分之2X=120
x+2/3x=60 x-2/5x=120 4x+18x=132
