Question

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 find the value of x, we need to isolate x on one side of the equation. We can do this by adding the same number to both sides of the equation.

Let's add 78 to both sides of the equation:

x - 78 + 78 = -5 + 78

This simplifies to:

x = 73

So, the number that needs to be added to both sides of the equation is 78.
