(5,y) (x,2)

Answer 1

X=10 Y=1

thats your answer hope it helps ;P

Answer 2

3x - 5y = 20

(5; y) - put x = 5 to the equation

3 · 5 - 5y = 20
15 - 5y = 20 |-15
-5y = 5 |:(-5)
y = -1

Answer: (5; -1)

(x; 2) - put y = 2 to the equation

3x - 5 · 2 = 20
3x - 10 = 20 |+10
3x = 30 |:3
x = 10

Answer: (10; 2)
