Land areas

Two land areas are 244 m2. The first parcel is 40 m2 less than twice the second one. What has the acreage of each parcel?

Correct answer:

a =  149.3333 m2
b =  94.6667 m2

Step-by-step explanation:

a+b = 244
a = 2b - 40

a+b = 244
a = 2•b - 40

a+b = 244
a-2b = -40

a = 448/3 ≈ 149.333333
b = 284/3 ≈ 94.666667
