I have to find the value of X and Y in both questions. This is due today so please help ASAP!

Answer 1

2. x=5

y=10

3. x=21

y=4

Explanation:

2. 13y=20x+3y 10y=20x

8x+y=180-13y 14y=180-8x

y=2x plugging that into 14y=180-8x 28x=180-8x 36x=180 x=5

plug x into 10y=20x 10y=100 y=10

3. 3(x+y)=(4x-9) 3x+3y=4x-9 x=3y+9

5x=180-4x+9 9x=189 x=21

plug 21 into x=3y+9 21=3y+9 12=3y 4=y
