Question

If g(x) = 3(x − 2), find the value of x if g(x) = 6.

Answer 1

Kimm since the function is g(x) = 3(x-2) and we are given g(x)=6  That means:    6 = 3(x-2)    Then we need to know what is x?          6 = 3x - 6            (distribute the 3)         12 = 3x               (add 6 to both sides)          4 = x                  (divide both sides by 3)You can check it this way.    Is   g(4) = 3(4-2) = 6    ?                 3*2 = 6
