    pick 2 equations at a time and eliminate the same variable

    now I have eliminated the same variable and you have set with y and z

    suggest using substitution of y from (6) into (4) or use elimination (6)times 3 added to (4) will eliminate y either one will give one equation with one variable z

    use this value of z in the expression to get y

    you have z and y more substitution in any of the originals to get x
