Answer 2

To solve the equation (388 - 140) / x = 31, we need to isolate the variable x.

First, simplify the expression on the left side of the equation: (388 - 140) = 248

Now we have the equation: 248 / x = 31

To isolate x, we can multiply both sides of the equation by x: 248 = 31 * x

Next, divide both sides of the equation by 31: 248 / 31 = x

Simplifying the division gives us: x = 8

Therefore, the solution to the equation is x = 8.
