Question

find the three solition of the equation 4x+3y=12

Answer 1

he given equation is 4x + 3y = 12

For x=0, 

4×0 + 3y = 12

⇒ 3y = 12 - 0

⇒ 3y = 12

⇒ y = 12/3 

⇒ y = 4

So (0,4) is a solution.

For x=1, 

4×1 + 3y = 12

⇒ 3y = 12 - 4

⇒ 3y = 8

⇒ y = 8/3 

So (1,8/3) is a solution.

For x=2, 

4×2 + 3y = 12

⇒ 3y = 12 - 8

⇒ 3y = 4

⇒ y = 4/3 

So (2,4/3) is a solution.

For x=3, 

4×3 + 3y = 12

⇒ 3y = 12 - 12

⇒ 3y = 0

⇒ y = 0/3 

⇒ y = 0

So (3,0) is a solution.

Four solutions are: (0,4); (1,8/3); (2,4/3); (3,0)

Answer 2

hey Frnd here is your answer :-

3y = 12 - 4x

y = 12 - 4x / 3 ( I ) Put x = 0

3y = 12 - 4x

3y = 12 - 4 (0)

3y = 12 - 0

3y = 12

y = 12/3

y = 4 therefore Ist sol. ( 0,4 )

( II ) Put x = 1

3y = 12 - 4x

3y = 12 - 4 ( 1 )

3y = 12 - 4

3y = 8

y = 8/3

y = 2.66 therefore 2nd Sol. ( 1,2.7 )

( III) Put x = 2

3y = 12 - 4x

3y = 12 - 4(2)

3y = 12 - 8

3y = 4

y = 4/3

y = 1.33 therefore 3rd Sol. ( 2,1.3 )
