Answer 1

Answer:

5x + 10y

Step-by-step explanation:

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

Answer 2

Answer:

$y=-\frac{1}{2}x$      OR      $x=-2y$

Step-by-step 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.  

$5x=-10y$

$x=\frac{-10y}{5}\\ x=-2y$

OR    

$5x=-10y\\y=-\frac{1}{2}x$
