Set the two equations equal to each other. Since they both equal y, they both equal each other. For instance if we have y=x and y=5, then x=5 since we can substitute 5 into y.
Substitute into
Now we have everything in terms of x. Solve for x.
Add 6 to both sides
Subtract 3/2x from both sides
Multiply both sides by 2
Substitute this back into
