Solve the system by substitution. 2x+y=-11 3x-4y=11

(3,5)

(-5,-3)

(-3,-5)

(5,3)

2x + y = - 11

y = - 2x - 11

3x - 4y = 11

3x - 4 (-2x - 11) = 11

3x + 8x + 44 = 11

11x = 11 - 44

11x = - 33

x = - 33/11

x = - 3

y = - 2x - 11

y = - 2 (-3) - 11

y = 6 - 11

y = - 5

solution is (-3,-5) <==
