Step-by-step explanation:
because if you distribute youll have 4x
Answer:4x+1=2x-5
First subtract 1 from each side.
4x+1-1=2x-5-5
That would be 4x=2x-10
Then divide by 2x on both sides
4x/2x=2x/2x-10
That would be 2x=-10
Then divide one more time by 2 on both sides
Like so, 2x/2=-10/2
Your answer is x=-5
