You need to do 2 at a time. Start with eq 2 & 3 2x y + 5x = 9 2x  10y  5z = 0 subtract 2 from 1 2x y + 5x = 9 2x + 10y + 5z = 0 ( i changed the signs so we can add instead) 9y + 10z = 9 Now we have to to 1 & 3 x + 5y  4z = 10 Multiply everything by 2 2x  10y  5z = 0 2x  10y + 8z = 20 2x  10y  5z = 0 (add them) 20y + 3z = 20
