x=9

Answer 3

To solve the equation 2x - (7 + x) = 2, we'll start by simplifying the expression on the left side and then isolating the variable x.

Step 1: Distribute the negative sign (-) to the terms inside the parentheses: 2x - 7 - x = 2

Step 2: Combine like terms: x - 7 = 2

Step 3: Move the constant term (-7) to the right side by adding 7 to both sides: x = 2 + 7

Step 4: Simplify: x = 9

Therefore, the solution to the equation 2x - (7 + x) = 2 is x = 9.
