What is the solution for x in the equation 5x + 15 = 50?

To solve the equation 5x + 15 = 50 for x, you start by isolating the variable term. This can be achieved by eliminating the constant on the left side of the equation.

First, subtract 15 from both sides of the equation:

5x + 15 - 15 = 50 - 15

5x = 35

Next, to find the value of x, divide both sides by 5:

5x / 5 = 35 / 5

x = 7

So the solution for x in the equation 5x + 15 = 50 is 7. This is why the correct answer is the one associated with 7, as it directly results from following the steps of algebraic manipulation accurately.
