**MathMate**, Saturday, August 1, 2009 at 11:46pmIn problems like this, you look for a variable which you can eliminate by adding the two equations multiplied by appropriate factors.

For the given problem, if you multiply the second equation and add the whole equation to the first, the "y" terms will cancel out leaving you with a single equation in x, which you can solve by transposition and finally division by the coefficient of x.

Once you have obtained the value of x, you will substitute this value to any of the two equations to result in an equation in y. Solve this equation for y and*substitute the values of x and y*back into the original equations as a check.

If you want to post your calculations and answers for checking or comments, you are welcome to do so.
