(30-x):(18+x)=(20+x):(32-x)
(x+30)*(x-18)=x*x
(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x
30/x=30/(x-1.5)-x
30x=30(32-x)
0.8x=x-30 x=
x ( x-30)= -67.5 X=?
x-30-0.2x=0.5x
3X+30+X+X-15=?
x+35=(x+3x)*30%
60x(x-4)=30x
80%x+30-x=10%x
X-30%X+8-X=20
30%x=50%x-20x
32-7X-5X=30
32+30%x+108=x
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)....
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)
