Question

solve graphically : 3x + y = 13 , x - 3y = -9​

Answer 1

Answer:

x = 17/3 and y = 4

x = 5.6 and y = 4

Step-by-step explanation:

we do this by elimination method

 3x + y = 13

- 3x + 9y = 27 (multiply equation by 3)

⇒ 10y = 40

⇒ y = 40/10

⇒   y = 4

put y = 4 in any equation

so, 3x + y = 13

⇒ 3x + 4 = 13

⇒ 3x = 17

⇒ x = 17/3

Answer 2

answer is 17/3 so go on i bet that is the answer
