To solve the equation \( x - 78 = -5 \) for \( x \), you can add 78 to both sides of the equation.
Hereβs how it looks:
-
Start with the equation: \[ x - 78 = -5 \]
-
Add 78 to both sides: \[ x - 78 + 78 = -5 + 78 \]
-
Simplifying gives: \[ x = 73 \]
So, the number that should be added to both sides is 78 in order to solve for \( x \).
