A farmer plants corn and wheat on a 180-acre farm. The farmer wants to plant three times as many acres of corn as wheat. Write a system of linear equations that represent this situation. How many acres of each crop should the farmer plant?

C=number of acres of corn

w=number of acres of wheat

total is 180 acres

c+w=180

wants to plant 3 times as many corn as wheat

c=3w

subsitute 3w for c in other

c+w=180

3w+w=180

4w=180

divide boh sides by 4

w=45

sub back

c=3w

c=3 (45)

c=135

135 acres of corn and 45 acres of wheat
