48:x+78=

To solve for x, we need to isolate it on one side of the equation.

Starting with the given equation:

48:x + 78 =

To isolate x, we need to move the 78 to the other side of the equation. Subtracting 78 from both sides:

48:x = -78

Now, to solve for x, we need to divide both sides of the equation by 48:

x = -78/48

Simplify the expression:

x = -1.625

Therefore, x is equal to -1.625.
