Building A and B

Question

Building A is 347 meters taller than building B. If the height of building A is subtracted from twice the height of building B, the result is 97 meters. How tall is each skyscraper?

Answer 1

A = B + 347

2B - A = 97

 

2B - (B + 347) = 97

B - 347 = 97

B = 444

 

Proof

 

A = 444 + 347 = 791

 

888 - 791 = 97
