To solve for x in the equation 45 = x - 12, the inverse operation needed is addition. Adding 12 to both sides of the equation will isolate the variable x.
To solve for x in the equation 45 = x - 12, we need to isolate the variable x on one side of the equation. To do so, we need to undo the operation that is being done to x.
In this case, x is being subtracted by 12. To undo this subtraction operation, we need to perform the inverse operation, which is addition.
By adding 12 to both sides of the equation, we can cancel out the subtraction and isolate x:
45 + 12 = x - 12 + 12
57 = x
So, the inverse operation needed to solve for x in this equation is addition.
