解方程
(1)x-7=10-4(x+0.5)
(2)x-1/2=4x/3
(3)5x+1/3-2x-1/6=1

(1)3x²+6x+5-4x²+7x-6解方程(1)x-7=10-4(x+0.5)(2)x-1/2=4x/3(3)5x+1/3-2x-1/6=1
(1)原式=(3x²-4x²)+(6x+7x)+(5-6)
=- x²+13x-1
(1)x-7=10-4(x+0.5)
x-7=10-(4x+2)
x-7=10-4x-2
x+4x=8+7
5x=15
x=3
(2)x-1/2=4x/3
x-1/2X6=4x/3X6
3x-3=8x
x= -5/3

1、不是等式怎么接啊?
1、x=3
2、x=-3/2
3、5/18

(1)x-7=10-4x-2
x+4x=10-2+7
5x=15
x=3
(2)x-1/2=4x/3
x-4x/3=1/2
-1x/3=1/2
x=-3/2
(3)5x+1/3-2x-1/6=1
5x-2x=1+1/6-1/3
3x=5/6
x=5/18
