Respuesta :

Without a value for [tex]y[/tex], we can only solve for [tex]x[/tex] in terms of [tex]y[/tex].

We have:

[tex]\frac{x+y}{3} = 5[/tex]

Multiplying by three gives:

[tex]x+y=15[/tex]

Then, subtracting y gives:

[tex]x=15-y[/tex]

Completing the solution.

(X+Y)(/3)=5

Since we don't know the value of Y, we can only solve for X in terms of Y.

X=15-Y
