Question

`\sf 3x+6y=12`​

Answer 1

x=2(3-y)

Explanation:

3x+6y=12

x+2y=4

x=4-2y

=2(2-y)

Answer 2

`3x + 6y = 12`

`3x + 6y - 6y = 12 - 6y`

`3x = 12 - 6y`

`(3x)/(3) = (12)/(3) - (6y)/(3)`

`(3x)/(3) = 1 = x`

`(12)/(3) - (6y)/(3)`

`= (12 - 6y)/(3)`

`= (6(2 - y))/(3)`

`(6)/(3) = 2`

`= 2( - y + 2)`

`x = 2( - y + 2)`
