回答1:

 7(2x-1)-3(4x-1)=4(3x+2)-22.
化简:
14x-7-12x+3 = 12x+8 -22.
2x-4=12x-14
10x=10.
x=1.

回答2:

7(2x-1)-3(4x-1)=4(3x+2)-22
14x-7-12x+3 = 12x+8-22
2x-4 =12x-14
2x-12x =-18
-10x=-18
10x=18
x=1.8

回答3:

先开括号:14x-7-12x+3=12x+8-22

移项:14x-12x-12x=8-22+7-3
结果:x=1

回答4:

14X-7-12X+3=12X+8
2X-4=12X-14
X=1

回答5:

解:(14x–7)–(12x–3)=(12x+8)–22
14x–7–12x+3 =12x+8–22
2x–4 =12x–14
-10x =-10
x = 1
