Use systems of equations to solve the problem.

A farmer raises wheat and oats on 180 acres. She plants wheat on 20 more acres than she plants oats on. How many acres of each crop does the farmer plants?

X + y = 180

Y = wheat, x = oats

Y = x + 20. In the 1st equation, get y by itself getting y = 180 - x.

So 180 - x = x + 20. Subtract x on both sides to get 180 - 2x is 20. Subtract 180 to both sides is - 2x = - 160. Divide - 2 to both sides is x = 80. So 80 + 20 is 100 wheat, and 80 oats of acres.

180-20=160:2=80

80 acres oats

100 acres wheat
