Question

The sum of two numbers is 56. the first number is 2/5 of the second number. Let x represent the first number and y represent the second number. choose the correct system of equations.

Answer 1

I believe it would be x + y = 56

Answer 2

Hello, 

x= first number
y= second number

their sum is 56, so:
x+y=56

The first number is 2/5 of the second number, so:
$x= \frac{2}{5}y$

Those are the two equations.
