In this question, we're given in a bike shop, there are three kinds of cycles, tricycles, bicycles and unicycles.
00:07
I'm going to let t be the number of tricycles, b be the number of bicycles and u be the number of unicycles.
00:28
Now we're given that the total number of wheels is 98.
00:31
So the total wheels equals to 98.
00:38
So we know that there are t number of tricycles.
00:42
So the number of wheels from the tricycles will be 3t plus.
00:51
Know that bicycles have two wheels.
00:54
So number of wheels from bicycles will be 2b plus.
01:01
Unicycle has one wheel.
01:03
So number of wheels coming from all the unicycles, there will be one u.
01:09
This is equals to 98.
01:12
So this will be equation 1.
01:14
Next, we are given that there are 46 seats and each of the cycles have 1 seat each.
01:19
So that means the number of tricycles t plus number of bicycles b plus number of unicycles u all have 1 seat each.
01:32
So it's equal to 46 seats.
01:34
So this is equation 2.
01:37
Next, we are given that there are twice as many bicycles as tricycles...
