I'll do the first one to get you started

# 1



6%28x-1%29=3x%2Bx%2B8 Start with the given equation.


6x-6=3x%2Bx%2B8 Distribute.


6x-6=4x%2B8 Combine like terms on the right side.


6x=4x%2B8%2B6 Add 6 to both sides.


6x-4x=8%2B6 Subtract 4x from both sides.


2x=8%2B6 Combine like terms on the left side.


2x=14 Combine like terms on the right side.


x=%2814%29%2F%282%29 Divide both sides by 2 to isolate x.


x=7 Reduce.

Answer:

So the answer is x=7
