Answer 1

-7(x-2)=3x-1
-7x+14=3x-1
-7x-3x=-1-14
-10x=-15
x=1,5


4(x-1)=6(1+x)
4x-4=6+6x
4x-6x=6+4
-2x=10
x=-5


5/6(x-1)=4
5/6x-5/6=4
5/6x=4+5/6
5/6x=4⁵/₆
x=5,8


-1/2(-x-6)=-x
1/2x+3=-x
1/2x+x=-3
1,5x=-3
x=-2


4x+7/2 - 5x-1/6=x+5
4x-5x-x=5-7/2+1/6
-2x=2⅔
x=-1⅓


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