Use elimination method....
form an equation of two variable by eliminating one variable from one pair of equation .
then after form another equation of two variables by eliminating same variable from another pair of equations.

now, you have two equations of two variables, use elimination method (or any method) to solve it.
after getting values of two variables, you can get the value of third variable easily..
