Which number should be added to both sides of the equation x-7=1 to find the value of x?

Answer 1

To solve the equation \( x - 7 = 1 \) for \( x \), you can add 7 to both sides of the equation. This will help isolate \( x \).

Here's the step-by-step process:

1. Start with the equation: \[ x - 7 = 1 \]

2. Add 7 to both sides: \[ x - 7 + 7 = 1 + 7 \]

3. Simplifying both sides gives: \[ x = 8 \]

So, the number that should be added to both sides of the equation is \( 7 \).
