Hi...

So with the TWO equalities given m(x) = 4x + 15 and m(x) = 7, the term m(x) is the value of the function with a given value of x and you can safely conclude that 4x + 15 = 7 and you can now solve for x

4x + 15 = 7

4x = 7 - 15 = -8

4x = -8

x = - 8/4 or -2

Check: For x = -2 ... 4(-2) + 15 = -8 + 15 = 7
