Question

To draw graph of 3x+6y= 12 Find y When x=2​

Answer 1

Answer:

3x + 6y = 13x + 6y = 12x

x = 2

3 * 2 = 6

6 + 6y = 12

6 + 6y = 12

6y = 12 - 6

6y = 6

y = 6/6 = 1

Answer 2

The value of y at x = 2 is 1

Given:

3x+6y= 12

To find:

To draw graph of 3x+6y= 12 Find y When x=2​

Solution:

Given that x value is 2  

To find y value substitute x = 2 in given equation 3x+6y= 12

At x = 2 given equation  

⇒ 3(2) + 6y = 12

⇒  6 + 6y = 12

⇒  6y = 12 - 6  

⇒  6y = 6  

⇒  y = 1  

The value of y at x = 2 is 1
