I can't see where you got the idea that you want to multiply by . Follow the procedure below:

Solve this one by substitution.



Then substitute in the second equation:



Multiply both sides by



Put in standard form and then solve the quadratic for



Then substitute each of the values of back into the original first equation to determine each of the associated values of .
