Answer:
x + y = 180
x = 3y
acres of corn = 135 acres
acres of wheat = 45 acres
Explanation:
Given that:
Total acres = 180
Acres of corn (x)
Acres of wheat (y)
x = 3y
x + y = 180 - - - (1)
x = 3y - - - - - - - (2)
From x =3y
3y + y = 180
4y = 180
y = 180 / 4
y = 45
x = 3y
x = 3(45)
x = 135
Hence ;
acres of corn = 135 acres
acres of wheat = 45 acres
