Question 48126
Write:
{{{2x-8y = 48}}} as a function of x. What you are really asked to do is to solve the equation for y.

{{{2x-8y = 48}}} Add 8y to both sides of the equation.
{{{2x = 8y+48}}} Now subtract 48 from both sides.
{{{2x-48 = 8y}}} Finally, divide both sides by 8.
{{{x/4-6 = y}}} Or:
{{{f(x) = x/4-6}}}
