Question

निम्नलिखित समीकरणों में से प्रत्येक समीकरण के चार हल लिखिए:
(1) 2x+y=7
(ii) Tix+y=9
(iii) x=
34y​

Answer 1

1) 2x +y = 7

x= 1

2*1 +y = 7

y= 5

x= 2

2 *2 +y = 7

4 + y = 7

y = 3

x= 3

2 *3 +y = 7

6 +y = 7

y = 1

x = 0

2*0 + y = 7

0 + y = 7

y = 7

2)

x+y =9

x= 1

1 + y = 9

y= 8

x = 2

2 + y = 9

y = 7

x= 3

3 +y = 9

y = 6

x =4

4 +y = 9

y= 5

3) x= 34 y

y = 0

x= 34 *0

x = 0

x = 0

0 = 34 y

0/ 34 = y

y =0

y= 1

x= 34 *1

x = 34

x=1

1 = 34 y

y = 1/34
