3x + 2y = 6 4x + y = 1 Solve the system of equations. (-4/5, 21/5) (8/11, -21/11) no solution
3x + 2y = 6 (equation 1) 4x + y = 1 multiply -2 on both sides: -8x - 2y = -2 (equation 2) adding up equation 1 and 2 the result is: -5x = 4 x = -4/5 y = 1 - 4x = 1 - 4(-4/5) = 1 + 16/5 = 21/5 The solution for the system 3x + 2y = 6 4x + y = 1 is (-4/5, 21/5)
