I need answer step by step someone help me

see below

Step-by-step explanation:

The second equation tells us x = y - 3 so when we plug in y - 3 for x in the first equation we get 4(y - 3) + 3y = -5 → 4y - 12 + 3y = -5 → 7y = 7 → y = 1. Plugging this value into the second equation we get x = y - 3 = 1 - 3 = -2.

(-2,1)

Step-by-step explanation:

4x+3y=-5

x=y-3

first, plug in  y-3 for x to find y:

4(y-3)+3y=-5

4y-12+3y=-5

7y-12=-5

7y=7

y=1

now, plug in 1  for y to find x:

4x+3*1=-5

4x+3=-5

4x=-8

x=-2

(-2,1)
