Graphical Approach to solve multi-step problems A farmer wants to know how many pigs and hens are on his farm. He asks his children to count the animals on the farm. His children determined that there are 70 heads of pigs and hens and 200 legs altogether.

Graphical Approach to solve multi-step problems A farmer wants to know how many pigs and hens are on his farm. He asks his children to count the animals on the farm. His children determined that there are 70 heads of pigs and hens and 200 legs altogether. How could the number of pigs and hens be determined?
