To solve the equation 78+x=115, you can follow these steps:
1. Start by isolating the variable x on one side of the equation. In this case, you want to move the 78 to the right side, so you subtract 78 from both sides of the equation.
78 + x - 78 = 115 - 78
x = 37
2. Simplify both sides of the equation to find the value of x. Adding or subtracting the same value to both sides of the equation maintains its equality.
Therefore, the solution to the equation 78+x=115 is x = 37.
