2×[(3X+45)/10] + 17 = X
2×[(3X+45)/10] + 17 = X
(3x+45)/5 +17=x
3x+45+85=5x
3x-5x=-85-45
-2x=-130
x=65
(3x+45)/5 +17=x
3x+45+85=5x
3x-5x=-85-45
-2x=-130
x=65
x-10=4(x-28) 3(x-28)=x+56+28 2(1.5x-30-20)=x 2(2x-20-45)=x-1
解方程3x-10/x-3 +4x-5/x-1=6x-17/2x-5 +8x-14/2x-3
3x-10/x-3 +4x-5/x-1=6x-17/2x-5 +8x-14/2x-3
