christopher is walking past a bike shop and looks inside. He sees some bicycles and some tricycles. He sees 32 seats and 77 whee

KATRIN_1 [288]

Bicycles: 1 seat and 2 wheels
Tricycles: 1 seat and 3 wheels

So with this, we will be making a system of equations. One representing the amount of seats and one representing the amount of wheels. Let x = bicycles and y = tricycles:

$x+y=32\\2x+3y=77$

With this, I will be using the substitution method. Firstly, subtract y on both sides of the first equation:

$x=32-y\\2x+3y=77$

Next, substitute x in the second equation for (32 - y) and solve for y:

$2(32-y)+3y=77\\64-2y+3y=77\\64+y=77\\y=13$

<u>In short, there are 13 tricycles.</u>

$\\ \rm\longmapsto \dfrac{x-3}{4}=\dfrac{x}{2}$

$\\ \rm\longmapsto 2(x-3)=4x$

$\\ \rm\longmapsto x-3=\dfrac{4x}{2}$

$\\ \rm\longmapsto x-3=2x$

$\\ \rm\longmapsto x-2x=3$

$\\ \rm\longmapsto -x=3$

$\\ \sf\longmapsto x=-3$
