Solve the equations - 9x + 2y = 23 and - 4x - y = - 3

(-1,7)

Step-by-step explanation:

-9x + 2y = 23

-4x - y = - 3

multiplying equation 2 by 2

-9x + 2y = 23

-8x - 2y = - 6

adding the two equation to cancel out y

-17x = 17

x = - 1

plugging back x = - 1 into the second equation

4 - y = - 3

-y = - 7

y = 7

y=7

x = - 1
