Question 1106880
You just substitute one variable's formula for the other.

You already have a formula for y.  Use the expression in the first equation.

YOU DO IT!  Solve for x.  Finish.



Just solve both equations for y in terms of x and use slope and y-intercepts to graph and find the intersection point.

Read it as well as you can.  Try on paper if you want (graph PAPER).
