Best ResponseYou've already chosen the best response.0well your second equation gives you the value of z substitute z into the other two equations now you have two equations to solve so you would then make y the subject using one of the two equations you have then substitute y into the other equation then you will get a value of x then substitute your value of x into the equation to get y then substitute x and y into original equations to get z
