Question

X+2y=6

solve for variable y

Answer 1

`y=-(1)/(2)x+3`

Explanation:

`x+2y=6\\\\x-x+2y=6-x\\\\0+2y=6-x\\\\2y=6-x\\\\(1)/(2)(2y)=(1)/(2)(6-x)\\\\y=(6)/(2)-(x)/(2)\\\\y=-(1)/(2)x+3`

Answer 2

y = -x/2 + 3

Explanation:

Rearrange the equation by making 2y on one side and the rest on the other

2y = -x + 6

Divide both sides by 2 to make 'y' on its own

y = -x/2 + 3
