this is what i have, but i need help on the equation.

let x = students let y= adults

x=y+150

x=3x+5y+150

150*3=450, 4730-450=4280, 4280/2=2140

the # of students is 2140+150=2290

4730-150=4

**drwls**, Monday, October 13, 2008 at 7:50pmYour second equation is completely wrong. The two equations should be

x = y + 150

3x + 5y = 4730

So, 3(y +150) + 5y = 4730

8y = 4280

Solve for y, then x.
