Question:
what is what is x and y
looks impossible... Hi Matthew, You have two equations in two unknowns, x and y, and the standard way to approach such problems is to "eliminate one of the unknowns" and change the problem to one involving a single equation in one unknown. I can see two ways to approach this particular problem, eliminate x or eliminate y. Eliminate x4x  6y = 10 Subtracting the second equation from the first results in Hence y = ^{6}/_{7} and substitution into either of the two equations you started with will yield x. Eliminate y 12x + 3y = 12 2x  3y = 5 and adding the two equations yields or Hence x = ^{17}/_{14} and substitution will yield y. I hope this helps, Penny
