To find the value of x, you need to isolate x on one side of the equation. To do this, you can add the same number to both sides of the equation.
Adding 78 to both sides of the equation x - 78 = -5, we get:
(x - 78) + 78 = (-5) + 78
x - 78 + 78 = -5 + 78
On the left side, the -78 and +78 cancel out, leaving us with just x:
x - 0 = 73
On the right side, -5 + 78 = 73, so the equation simplifies to:
x = 73
Therefore, the value of x is 73.
What number should be added to both sides of the equation x − 78 = −5 to find the value of x ?
