Answer 1

>> 3(2x-1)=-2(x+3)
6x-3=-2x-6
6x+2x=-6+3
8x=-3
x=-3/8

>>>3(x-2)-5(x-1)=-7
3x-6-5x+5=-7
-2x-1=-7
-2x=-7+1
-2x=-6  *(-1)
x=6/2=3

>>> 4(x+10)-2(x-5)=0
4x+40-2x+10=0
2x=-50
x=-25

>>>3(2x+1)=-2(x-3)
6x+3=-2x+6
6x+2x=6-3
8x=3
x=3/8

>>>15+3(x+2)=-7x+2(x-1)
15+3x+6=-7x+2x-2
3x+7x-2x=-2-21
12x=-23
x=-23/12

>>>> 6(x-3)-9(x-1)=5-(x+3)
6x-18-9x+9=5-x-3
-3x-9=-x+2
-3x+x=2+9 * (-1)
2x=-11
x= -17/2
