Question

The function f is defined by f(x) = 2 over 5x +10. For what value of x does f(x) = 30 ?

The correct answer is: 50


    f left parenthesis x right parenthesis equals 2 over 5 x plus 10
    f(x) = 30
    30 equals 2 over 5 x plus 10
    30 equals fraction numerator 2 x plus 50 over denominator 5 end fraction
    150 = 2x + 50
    100 = 2x
    x = 50
