x+(x-1.4)+1.5x=33.
x+(x-1.4)+1.5x=33.

x+(x-1.4)+1.5x=33.
x+(x-1.4)+1.5x=33.6
原式：x+x-1.4+1.5x=33.6
3.5x=33.6+1.4
3.5x=35
x=10

x+(x-1.4)+1.5x=33. x+ x+(x*50%)=1.5X? （X+X)+(X-X)+(X*X)+(X/X)=100 x*x*x*x*x=80000? 1.4x-x=9.8求x 1.5x=x-1.6＊x 30/x=30/(x-1.5)-x 2X(x+1.5x)=5x 解方程 (2x+x+x/1.5)*4=110求x 2+X=1.4X x+18=1.4x x-0.3x=1.4 x-1.5x=56 6.5x+x=1.5 x+12=1.5x 1.5x+x=12. X+1.5%X=7.5 X+1.5X=35
