Here's my system of equations:

2w + 2L = 190

1/4L = w

What would I do from here? I prefer the elimination method. Would I multiply the second equation by 4? When I did so, it kind of messed up the equation.

Thanks! :)

**Reiny**, Monday, February 23, 2009 at 4:06pmI would use substitution, but if you insist on using elimination, multiplying the second equation by 4 gives you

L = 4W or 4W - L = 0

now double that:

8W - 2L = 0 , now the first:

2W + 2L = 190, now add them

.

.

I'm sure you can finish it.

**Willow**, Monday, February 23, 2009 at 4:09pmDid you get w = 19 and L = 76?

Thanks! :)
