142=58-7x

2x+96=-44-3x

-26=-7x+4(2x-4)

7x+5(-4x-4)=-124

-7x-35=28

10x+36=-108-2x

Add 7x to each side

7x+142=58-7x+7x

7x+142=58

Now subtract 142 from each side to isolate x

7x+142-142=58-142

7x=-84

Divide by 7 to find x

7x/7 = -84/7

x = -12

Now you should be able to try the remaining problems the same way as above and post your answers for checking.
