Answer 2

Answer:

(1,1) , (2,3/5) , (3,1/5) , (0,7/5)

Step-by-step explanation:

putting x = 1 in equation

2×1 + 5y = 7

2+5y = 7

5y = 5

y = 1

first solution is (1,1)

putting x=2 in equation

2×2 + 5y = 7

4 + 5y = 7

5y = 3

y = 3/5

putting x=3 in equation

2×3 + 5y = 7

6 + 5y = 7

5y = 1

y = 1/5

putting x =0 in equation

2×0 + 5y = 7

5y = 7

y = 7/5
