Question 418690

let the number of the cars in country {{{A}}} be {{{x}}}, and the number of the cars in country {{{B}}} be {{{y}}}

In country A, about five times as many cars are manufactured per day than in country B. 

{{{x=5x}}}..........1

If the total number of these cars manufactured per day is  {{{39624}}}, 

{{{x+y=39624}}}.........2

fine the number manufactured in country B and the number manufactured in country A.


{{{x=5y}}}..........1


{{{x+y=39624}}}.........2...solve this system by substituting {{{x}}} from 1 in 2

{{{5y+y=39624}}}...solve for {{{y}}}

{{{6y=39624}}}

{{{y=39624/6}}}

{{{y=6604}}}.......now find {{{x}}}


{{{x=5y}}}..........1

{{{x=5*6604}}}

{{{x=33020}}}

the number manufactured in country B is {{{y=6604}}}
the number manufactured in country A is {{{x=33020}}}

check:

{{{x+y=39624}}}.........2

{{{33020+6604=39624}}}

{{{39624=39624}}}
