This would be a great question to just plug into a calculator. I'm sure you will find the answer quite easily if you use a calculator.
Hey. Why are you so worried. Here is the answer. There is a very small problem.It is that the decimal point is not added.
C. formula
I hope this helps, thank you.
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.
