Some help is this:
(a) gives you y=2x-3. Substitute in (b) and you have,
simplifying to...
.
Can you factor this and find x values? If not factorable, you can use the general solution of a quadratic equation and find the x values. Use them to get the corresponding y values.
(5x 1)(x 1)... NOT factorable.
