What number should be added to both sides of the equation x−7=1

to solve for the value of x
?

2 answers

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

Here’s how it works:

  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 \( 7 \).
