Question

Write four solutions of the equation: 2x + y = 7



​

Answer 1

Given:-

2x + y = 7

To Find:-

4 solutions

Solution:-

If x = 0

2(0) + y = 7

0 + y = y

∴y = 7

If x = 1

2(1) + y = 7

2 + y = 7

y = 7 - 2

∴y = 5

If x = 7

2(7) + y = 7

14 + y = 7

y = 7 - 14

∴y = -7

If x = 2

2(2) + y = 7

4 + y = 7

y = 7 - 4

∴y = 3

Hence The four solutions are

7

5

-7

3

Answer 2

Answer:

The 4 solutions can be :-

a. x= 0 and y= 7

b. x= 1 and y= 5

c. x= 2 and y= 3

d. x= 3 and y= 1

Hope it helps you :)
