Question

Find four solutions of the following equations :

3x + 4y = 12​

Answer 1

Step-by-step explanation:

Let x=1

Therefore,

3×1+4y=12

3+4y=12

4y = 12-3

4y= 9

y= 9/4

Now, Let x=2

3×2+4y=12

6+4y=12

4y=12-6

y=6/4

y=3/2

Again,

Let x=3

3×3+4y=12

9+4y=12

4y=12-9

4y=3

y=3/4

Fourth Solution:

Let x=4

3×4+4y=12

12+4y=12

4y=12-12

4y=0

y=0/4

y=0

I hope this will help you.

Answer 2

Equation : 3x + 4y = 12

Let's keep value of x = 4 and y = 0

So, 3(4) + 4(0) = 12

12 = 12

Now, keep value of x = 8 and y = - 3

3(8) + 4(-3) = 12

24 - 12 = 12

12 = 12

Now, let's keep value of x = 0, y = 3

3(0) + 4(3) = 12

12 = 12
