Question

write any four solution for the equation x+2y =7

Answer 1

Step-by-step explanation:

For any solution we will put a value of y and by solving we will find the corresponding value of x.

This is a straight line and has infinite number of solutions.

For example,

y=1

x=7−2(1) =5

Hence, (5,1) is one of the solution of the given equation.

Answer 2

Answer:

when x = 0 , 1, 2 , 3 ; y = 7/2 , 3 , 5/2 , 4/3

Step-by-step explanation:

x+2y = 7

if we take x=0 we get 0 + 2y = 7 , 2y=7-0 ,  y=7/2

if we take x=1 we get 1+2y = 7 , 2y =7-1 ,  y=3

if we take x=2 we get 2+2y=7 , 2y = 7-2 ,  y=5/2

if we take x=3 we get 3+3y = 7 , 3y = 7-3  ,  y=4/3
