634-(156-x)=548

To solve the equation 634 - (156 - x) = 548, we follow the order of operations (also known as PEMDAS).

1. Start by simplifying the expression inside the parentheses: 156 - x = 156 - x.

2. Now, rewrite the equation: 634 - (156 - x) = 548 as 634 - 156 + x = 548.

3. Simplify further: 634 - 156 = 478, so the equation becomes 478 + x = 548.

4. To isolate x, subtract 478 from both sides of the equation: 478 + x - 478 = 548 - 478.

   This will give us x = 70.

Therefore, the solution to the equation 634 - (156 - x) = 548 is x = 70.
