Answer: for the 2 one x= 4 /5y + -16/5
for the first one x=−4y−8
Are they 2 sperate questions?
If yes here
1. x + 4y = -8
4y=−8
Step 1: Add -4y to both sides.
x+4y+−4y=−8+−4y
x=−4y−8
Answer:
x=−4y−8
2. 5x - 4y = -16
5x−4y=−16
Step 1: Add 4y to both sides.
5x−4y+4y=−16+4y
5x=4y−16
Step 2: Divide both sides by 5.
5x = 4y- 16
5 5
5 x/4 = 5y + -16
5
x= 4 /5y + -16/5
