Question

what are the coordinate of the point of intersction of the lines x+3y=7 and 2x+y=1​

Answer 1

Answer:-

x = -2

y = 3

Step-by-step explanation:-

x + 3y = 7

2x + y =  - 1

x = 7 - 3y

2(7 - 3y) + y =  - 1

⇒ 14 - 6y + y =  - 1

→14 - 5y =  - 1

⇒ 5y = 15

→ y = 3

x = 7 - 3(3)

⇒ x =  7 - 9

→ x =  - 2
