Question 8985: Hi, could you please help me on a problem that I have. I do not need to solve this problem, I just need to put it into an equation. This is the problem: The height of a tower is three times the height of a certain building. If the tower is 50 m taller than the building, how tall is the tower?
I tried to work out the problem: I used b for my variable. Then I used 3b for the tower height, and b for the building height (I'm in the beginning of Algebra 1, so we are suppose to use only 1 variable).
Then I put together this equation: 3b - b = 50 m. Could you please tell me if this is right, and also add how you get it? Thank you so much!!

You can put this solution on YOUR website! It looks right to me. To finish, just solve the equation:
3b - b = 50
Remember that b = 1b, so 3b - 1b = 2b
2b = 50
b= 25 feet= height of the building
3b = 75 feet = height of the tower.
Check: You said that the tower is supposed to be 50 feet taller than the building, which indeed it is!! So you got it right, and it checks! Nice work!!
