Answer :

Answer:

x = 200

Step-by-step explanation:

[tex]x - y = 80 \: \: and \: \frac{3}{5} = \frac{y}{x} [/tex]

x = 80 + y, then

[tex] \frac{3}{5} = \frac{y}{80 + y} [/tex]

3(80 + y) = 5y

240 + 3y = 5y

240 = 5y - 3y = 2y

Divide both sides by 2

y = 120, therefore

x = 80 + 120 = 200

x = 200
