11x-4.5=7.
4.5x +x=17分之11 求x是多少?
4.5x+x=17分之11
4.5x+x=17/11
4.5x+x=11/17
4.5x+x=11/17求解
4.5x+x=11/17
8x+5x=1.3 4.5x-3.2x=3.9 5.5x-x=9.9 11x-7x-26=34 列方程
1.25-x=2.8 2.36÷x+9=0 3.33x=79-x 4.5x-(11-7)=x+3 5.169÷(x+9)
x+24=4.5X
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
解方程:1/(x*x+11x-8)+1/(x*x+-8)+1/(x*x-3x-8)=0
