Answer 2

Let's solve the equation step by step.

2x - 3(1 + x) = 5 + x

First, distribute the -3 across the parentheses:

2x - 3 - 3x = 5 + x

Combine like terms:

(2x - 3x) - 3 = 5 + x

-x - 3 = 5 + x

Now, let's isolate the x terms on one side and the constant terms on the other side.

Add x to both sides:

-x + x - 3 = 5 + x + x

Simplifying:

-3 = 5 + 2x

Next, subtract 5 from both sides:

-3 - 5 = 5 + 2x - 5

Simplifying:

-8 = 2x

To isolate x, divide both sides of the equation by 2:

-8/2 = 2x/2

Simplifying:

-4 = x

So the solution to the equation is x = -4.
