3x-4y=-24 and x+y=-1

x = - 4, y = 3.

Step-by-step explanation:

3x - 4y = - 24 ... (1).

x + y = - 1 Multiply this equation by - 3:-

-3x - 3y = 3 ... (2)

Adding (1) and (2):

-7y = - 21

y = 3.

Substitute y = 3 in equation (1):

3x - 4 (3) = - 24

3x = - 24 + 12

3x = - 12

x = - 4.

3x - 28 = - 24

3x = 4
