Building A is 255 meters taller than building B. If the height of building A is subtracted from twice the height of building B, the result is 234 meters. How tall is each

skyscraper?

A = 744 meters B = 489 meters

Step-by-step explanation:

A = B + 255

2B - A = 234

-2B - 2B Subract the - 2B from both sides

-A = - 2B + 234

A = 2B - 234 Divide by - 1 to get A alone

B + 255 = 2B - 234 Set both equations equal to each other

- B - B

255 = B - 234

+234 + 234

489 = B

Plug 234 in for B in the original equations

A = 489 + 255

A = 744
