Question

Work-Out Corner has 5 more than 3 times as many exercise bicycles as The Gym. Together they have 21 bicycles. Solve the equation x + 3x + 5 = 21 to find the number of bicycles at Work-Out Corner.

Answer 1

add the x variables, subtract 5 from each side...

Answer 2

4x+5=21
4x=16

Answer 3

yep.....so x = ?

Answer 4

4?

Answer 5

now use the first line of the problem. "WOC has 5 more than 3 times The Gym..." (that is 3x + 5, algebraically), where x is equal to the number of bikes at The Gym

Answer 6

so knowing the gym has 4 bikes, you can substitute that value into 3x+5 to find the answer!
