What number should be added to both sides of the equation x − 78 = −5 to find the value of x ?
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.
To find the value of x, we need to isolate the variable on one side of the equation.
To do this, we can add the same number to both sides of the equation.
In this case, to eliminate the -78 on the left side of the equation, we need to add 78 to both sides of the equation.
So the number that should be added to both sides of the equation x - 78 = -5 is 78.
To find the value of x in the equation x - 78 = -5, we need to isolate x by getting rid of the -78 on the left side of the equation. Since the -78 is being subtracted from x, we can undo this operation by adding 78 to both sides of the equation. This ensures that we maintain the balance of the equation.
So, to find the value of x, we add 78 to both sides of the equation:
x - 78 + 78 = -5 + 78
This simplifies to:
x = 73
Therefore, the value of x is 73.
