Define variable and write a system of equations for this situation. Solve using substitution.
A farmer grows only sunflowers and flax on his 240-acre farm. This year he wants to plant 80 more acres of sunflowers than that of flax. How many acres of each crop does the farmer need to plant?
let the number of acres for flax be f
let the number of acres for sunflowers be s
s + f = 240
f = s - 80
take it from there.
