What number should be added to both sides of the equation x − 78 = −5 to find the value of x ?(1 point)

Answer 1

To solve the equation \( x - 78 = -5 \), you can add a number to both sides to isolate \( x \).

We want to find a number to add to both sides. In this case, you can add 78 to both sides:

\[ x - 78 + 78 = -5 + 78 \]

This simplifies to:

\[ x = -5 + 78 \]

Now, calculate the right side:

\[ x = 73 \]

To find out what number we added to both sides, we can see that we added 78.

So, the answer is 78.
