Question 62913
 QUESTION:

rewrite this as a function of x 
4x-6y= - 30

ANSWER:

4x-6y= - 30

Subtract 4x from both sides of the expression

==> 4x-6y -4x = - 30 - 4x

==>4x-4x -6y = - 30 - 4x

==> -6y = - 30 - 4x

Now divide whole expression by -6

==> -6y/-6 = - 30/-6 - 4x/-6

==> y = 5 + (4/6)x

which is  a function of x.
