if (x,y) is a solution to the equation 3(x+y)=y what is the value of x over y

Answers

Answer 1

Answer:

-2/3

Explanation:

3(x+y) = y

3x + 3y = y

3x = -2y

x = (-2/3)y

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

Double check:

x = -2

y = 3

3(-2+3) = 3

3(1) = 3

3=3

Answer 2

[tex]\displaystyle\ 3(x+y)=y \\\\3x+3y=y\\\\ 3x=-2y\\\\\boxed{x=-\frac{2}{3} y \ \ or \ \ y=-1.5x}[/tex]
