Find the value of x so that the function has the given value. n(x) = 2x + 7, n(x) = 17

Answer :

Substitute n(x) = 17 in ; n(x) = 2x + 7 and then solve for x

That is;

n(x) = 2x + 7

17 = 2x + 7

subtract 7 from both-side of the equation

17 - 7 = 2x

10 = 2x

divide both-side of the equation by 2

10/2 = 2x/2

x = 5
