Answer 3

To solve the equation 3x - (x + 5) = 2(x + 1), you'll need to simplify and isolate the variable x. Here are the steps to solve it:

1. Distribute the 2 on the right side of the equation:

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

2. Remove the parentheses by distributing the negative sign inside the parentheses on the left side:

3x - x - 5 = 2x + 2

3. Combine like terms on both sides of the equation. Subtract 2x from both sides and add 5 to both sides:

3x - x - 2x - 5 + 5 = 2x - 2x + 2 + 5

This simplifies to:

2x - 5 = 7

4. Now, isolate x by adding 5 to both sides of the equation:

2x - 5 + 5 = 7 + 5

This simplifies to:

2x = 12

5. Finally, divide both sides by 2 to solve for x:

2x/2 = 12/2

x = 6

So, the solution to the equation is x = 6.
