w + s = 270

7s - 2w = 0

w is the number of acres planted with wheat, and s is the number of acres planted with soybeans.

How many acres should the farmer plant with soybeans?

I came up with 52

Is this correct?

**Reiny**, Monday, April 25, 2011 at 5:38pmeasier way:

the ratio of soybeans : wheat = 2 : 7

let the number of acres of soybeans be 2x

let the number of acres of wheat be 7x

2x + 7x = 270

9x = 270

x = 30

so acres of soybeans = 2(30) = 60

acres of wheat = 7(30) = 210
