0.7x+1.73=1.5x-0.230.7x+1.73=1.5x-0.230.7x+1.73=1.5x-0.230.7x+1.73=1.5x-0.231.73+0.23=1.5x-0.7x1.96=

0.7x+1.73=1.5x-0.23
0.7x+1.73=1.5x-0.23

0.7x+1.73=1.5x-0.23
0.7x+1.73=1.5x-0.23
1.73+0.23=1.5x-0.7x
1.96=0.8x
所以
x=1.96/0.8
=2.45

0.7x+1.73=1.5x-0.23 0.7x+1.37=1.5x-0.23 x=? x+ x+(x*50%)=1.5X? 解方程：0.7x+1.37=1.5x-0.23 1.5x-0.7=6.5-1.3x x-0.7x=1.5怎么算（X+X)+(X-X)+(X*X)+(X/X)=100 x-0.7x=64.8求x 1.5x=x-1.6＊x x+(x-1.4)+1.5x=33. 30/x=30/(x-1.5)-x x-0.23x=1.54, 5(x-1)=x+1 0.4(x-0.2)+1.5=0.7x-0.38 x-0.7x=18 x-0.7x=0.51 x-0.7x=1.02 x-0.7x=1. x-0.7x=0.24.
