Question

Which expression is equivalent to 5x + 5y + 5y?

Answer 1

5x + 10y

Explanation:

5x + 5y + 5y = 5x + 10y

Answer 2

`y=-(1)/(2)x \\` OR
`x=-2y`

Explanation:

Given :

`5x + 5y + 5y\\`

We have to find the equivalent expression of the above equation.

Equating the expression to zero

`5x + 5y + 5y=0\\`

Adding the terms of 'y'

`5x+10y=0\\`

Taking the terms of 'x' to one side and 'y' terms to the other side.

`5x=-10y`

`x=(-10y)/(5)\\ x=-2y`

OR

`5x=-10y\\y=-(1)/(2)x`
