Answer 1

The number of hamburgers is 136.

Explanation:

What we know:

We got cheeseburgers and hamburgers

The total: 408

The number of cheese burgers was 2 times the number of hamburgers

This is pretty much all the info we need to know.

Lets define our variables:

x = hamburgers

y = cheeseburgers

Now, we need our two equations to make a system.

`x+y=408`

`y=2x`

To find hamburgers, x, we plug the value of y into our first equation.

`x+2x=408`

Add like terms

`3x=408`

Divide by 3

`x=136`

The number of hamburgers is 136.

Just to check our work, lets find the cheeseburgers.

`y=2(136)`

`y=272`

`272+136=408`
