Question

如题所述

Answer 1

3-x/2=x+4/3
3-4/3=x+x/2
5/3=3x/2
x=10/9

1/3(x+1)=1/7(2x-3)
7(x+1)=3(2x-3)
7x+7=6x-9
x=-16

x+2/5=x/4
x-x/4=-2/5
3x/4=-2/5
x=-8/15

1/4(x+1)=1/3(x-1)
3(x+1)=4(x-1)
3x+3=4x-4
x=7

( 2x-1)/3=(x+2)/4-1
4(2x-1)=3(x+2)-12
8x-4=3x+6-12
5x=-2
x=-2/5

1/2(x-1)=2-1/5(x+2)

5(x-1)=20-2(x+2)
5x-5=20-2x-4
7x=21
