计算:(3x+2)/5-(x-6)=x/3计算:(3x+2)/5-(x-6)=x/3计算:(3x+2)/5-(x-6)=x/3(3x+2)/5-(x-6)=x/33(3x+2)-15(x-6)=5x9

计算:(3x+2)/5-(x-6)=x/3
计算:(3x+2)/5-(x-6)=x/3

计算:(3x+2)/5-(x-6)=x/3
(3x+2)/5-(x-6)=x/3

3(3x+2)-15(x-6)=5x
9x+6-15x+90-5x=0
-11x+96=0
-11x=-96
x=96/11

等式两边都乘15得:3(3x+2)-15(x-6)=5x
9x+6-15x+90=5x
11x=96
x=96/11
