Two lands

The common area of the two neighboring lands is 964 m2. The second land is 77 m2 smaller than twice the size of the first land. Find the areas of each land.

Correct result:

a =  347 m2
b =  617 m2

Solution:


a+b=964
b = 2a - 77

a+b=964
b = 2•a - 77

a+b = 964
2a-b = 77

a = 347
b = 617

Our linear equations calculator calculates it.
b=617=617 m2
