The gym has a total of 25 treadmills and stationary bikes. There are 7 more stationary bikes than treadmills. How many treadmills are there, how many stationary bikes are there?

Question

I need to know how to find those two and solve them.

Answer 1

B = 7 + T 7 more bikes than treadmils

B+T = 25 they sum to 25

substitute 7+T for B

7+T+ T= 25

2T = 25-7 = 18

T= 18/2 = 9 treadmills

B =9+7 = 16 bikes

9+16 =25 total
