x-3y=8
substitution method
​

Answer 1

Answer

(x−3y=8)×3

⇒3x−9y=24

(-)3x-5y=16                       

________

        -4y=8             ⇒y=−2

x−3y=8⇒x=3y+8=−6+8=2⇒x=2

Answer 2

Step-by-step explanation:

3x-5y=16 and x-3y = 8

making x equal

3x - 5y = 16 and 3x-9y = 24

= -4y = 8

= -y = 2 or y = -2
