Question 387715: To reproduce an old photograph, a photographer charges x dollars to make a negative, 3x/5 dollars for each of the first 10 prints, and x/5 dollars for each print in excess of 10 prints.

Value of x means to solve for x, right? this is how I initially set up the equation:
45=x + 3x/5 + x/5(10) which became 45=x + 3x/5 + 10x/5
