Sleek Meadows Horse Farm plants 31 acres of hay and oats. The owners know that their needs are best met if they plant 9 acres more of hay than oats. How many acres of each should they plant?
Let
x ------> acres of hay
y -----> acres of oats
we have that
x+y=31
x=31-y -------> equation A
x=y+9 ------> equation B
equate both equations
31-y=y+9
solve for y
y+y=31-9
2y=22
y=11
Find the value of x
x=y+9
x=20
therefore
