Answer 2

To solve for x in the equation 4x - (5 - x) = 3 + x, follow these steps:

1. Distribute the negative sign inside the parentheses:

4x - 5 + x = 3 + x

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

4x + x - 5 = 3 + x + x

This simplifies to:

5x - 5 = 3 + 2x

3. Now, isolate the terms with x on one side and the constants on the other side. To do this, subtract 2x from both sides:

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

This simplifies to:

3x - 5 = 3

4. Add 5 to both sides of the equation to isolate the variable term:

3x - 5 + 5 = 3 + 5

This simplifies to:

3x = 8

5. Finally, divide both sides by 3 to solve for x:

(3x)/3 = 8/3

x = 8/3

So, the solution to the equation is:

x = 8/3
