Question

2. Write four solutions for each of the following equations:

(i) 2x+y = 7​

Answer 1

Answer:

1) If x is 0,

2*0 + y = 7

y = 7

2) If x is 1,

2*1 + y = 7

y = 7-2 = 5

3) If x is 2,

2*2 + y = 7

y = 7-4 = 3

4) If x is 5,

2*5 + y = 7

y = 7-10 = -3

Final answers :

1) x = 0, y = 7

2) x = 1, y = 5

3) x = 2, y = 3

4) x = 5, y = -3
