-5y + 11 = 2x 5y + 3 = -9x ---------------add 14 = - 7x -14/7 = x -2 = x 5y + 3 = -9x 5y + 3 = -9(-2) 5y = 18 - 3 5y = 15 y = 15/5 y = 3 solution is : (2,3) ========================== 2x + 3y = 4....multiply by -2 4x + 6y = 9 -------------- -4x - 6y = -8 ...result of multiplying by -2 4x + 6y = 9 --------------add 0 = 1....(incorrect) there is no solution for this system
