Find the solution of the equation x+2y = 6 from the options given below
A. (0,3),(6,0),(2,2) and (4,1)
B. (0,2),(6,0),(2,2) and (4,1)
C. (0,3),(6,0),(2,2) and (3,1)
D. (0,3),(6,0),(1,2) and (4,1)
Answer: A
(0,3),(6,0),(2,2) and (4,1)
Solution
The given equation is x + 2y = 6…… (1)
Putting x = 0 in equation 1, we have
0 + 2y = 6
2y=6
y=3
(x,y) = (0,3)
(0,3) is a solution
Putting y=0 in equation 1, we have
x + 2 X 0 =6
x=6
(x,y) = (6,0)
(6,0) is a solution
Putting x = 2 in equation 1,we get
2 + 2y = 6
2y = 6 – 2
2y = 4
y=2
(x,y) = (2,2)
(2,2) is a solution
Putting x = 4 in equation 1, we get
4 + 2y = 6
2y = 2
y=1
(x,y) = (4,1)
(4,1) is a solution
