Idon't know how to do this i could really use some i would really appreciate it

Remember you can do anything to an equation as long as you do it to both sides

ok, what I would do is undistribute that 2 from the parentahsese then divide both sides by 4 but that's too complex so

distribute, remember that a(b+c)=ab+ac

so
-8+8b=-4+4b+8
combine like terms
-8+8b=4b+4
minus 4b from both sides
-8+4b=4
add 8 to both sides
4b=12
divide both sides by 4
b=3

-8(1-b)=2(-2+2b)+8

Apply the distributive property on both sides.
-8+8b=-4+4b+8

Simplify like terms
-8+8b=4+4b

Add 8 to both sides
8b=12+4b

Subtract 4b from both sides
4b=12

Divide both sides by 4
b=3
