Question

2. Which of the following is a solution of the equation
x + 2y = 7​

Answer 1

Answer:

2x+y=7 are (0,7) (1,5) (2,3) (3,1) hence four solutions for equations x=4y x =4 are (0,0) (1,4) (-4,_1) (8,2)

Answer 2

Step-by-step explanation:

Given equation is

x+2y=7

Putting y=2

x+2×2=7

x+4=7

x=7-4

x=3

First solution(x,y)=(3,2)

x+2y=7

Putting y=3

x+2×3=7

x+6=7

x=7-6

x=1

Second Equation (x,y) =(1,3)
