Construction 4727

Honza had 19 wheels in the kit. He used them all in the construction of tricycles and scooters. How many complete scooters and how many tricycles? He will find all the solutions.

Correct answer:

t₁ =  1
d₁ =  8
t₂ =  3
d₂ =  5
t₃ =  5
d₃ =  2

Step-by-step explanation:

$t_1=1$

$d_1=(19-3\cdot t_1)/2=(19-3\cdot 1)/2=8$

$t_2=3$

$d_2=(19-3\cdot t_2)/2=(19-3\cdot 3)/2=5$

$t_3=5$

$d_3=(19-3\cdot t_3)/2=(19-3\cdot 5)/2=2$
