Question

find two solutions for each linear equations (a) 4x + 3y = 12​

Answer 1

Answer:

(0,4) , (1,8/3).

Explanation:

4(0) +3y =12 ⇒ 3y =12. ⇒ y = 12 / 3 = 4. So, (0, 4) is a solution of given equation. ...

4(1) + 3y=12 ⇒ 3y = 12 - 4 = 8 ⇒ y = 8 / 3. So, (1,8 / 3) is another solution of the given equation. ...

Answer 2

Answer:

Two solutions are (0,4) and (3,0)

Explanation:

4x+3y=12

Now

$x = \frac{12 - 3y}{4}$

Putting y=4 we get x=0

Also putting y=0 we get x=3

Thus these are the two solution of the given equation.
