Answer:
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)
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
