2x + 9y = 0 3x + 5y = 17 multiply the first equation by 3 and the second by 2; then subtract 6x + 27y = 0 6x + 10y = 34 17y = -34 y = -2 substitute to find 'x' 2x + 9(-2) = 0 2x -18 = 0 2x = 18 x = 9 check by substituting these values into the other equation 3(9) + 5(-2) = 17 ?? 27 -10 = 17 Answer: (9,-2) Do you wanna know how to graph it?
