$\"19\"$ = number of 1-point baskets/shots
\n" ); document.write( " $\"x\"$ = number of 2-point baskets/shots
\n" ); document.write( " $\"y\"$ = number of 3-point baskets/shots
\n" ); document.write( " $\"19%2B2x%2B3y\"$ = total number of points scored.
\n" ); document.write( "\"Team scored 78\" translates as
\n" ); document.write( " $\"19%2B2x%2B3y=78\"$
\n" ); document.write( "We translate \"the remaining 27 were two points or three point shots\" as
\n" ); document.write( " $\"x%2By=27\"$ .
\n" ); document.write( "We have a system of two equations: $\"system%2819%2B2x%2B3y=78%2Cx%2By=27%29\"$ .
\n" ); document.write( "You could easily solve $\"x%2By=27\"$ for $\"x\"$ :
\n" ); document.write( " $\"x%2By=27\"$ ---> $\"x=27-y\"$ ,
\n" ); document.write( "and then substitute $\"27-y\"$ for $\"x\"$ in the other equation to get
\n" ); document.write( " $\"19%2B2%2827-y%29%2B3y=78\"$
\n" ); document.write( " $\"19%2B54-2y%2B3y=78\"$
\n" ); document.write( " $\"73%2By=78\"$
\n" ); document.write( " $\"y=78-73\"$
\n" ); document.write( " $\"highlight%28y=5%29\"$ .
\n" ); document.write( "Then, substituting $\"5\"$ for $\"y\"$ in $\"x=27-y\"$ , you get
\n" ); document.write( " $\"x=27-5\"$
\n" ); document.write( " $\"highlight%28x=22%29\"$ .
\n" ); document.write( "
\n" ); document.write( "NOTE:
\n" ); document.write( "If you have not studied systems of equations,
\n" ); document.write( "you could start with
\n" ); document.write( " $\"19\"$ = number of 1-point baskets/shots
\n" ); document.write( " $\"y\"$ = number of 3-point baskets/shots,
\n" ); document.write( "and since \"the remaining 27 were two points or three point shots\"
\n" ); document.write( " $\"27-y\"$ = number of 3-point baskets/shots
\n" ); document.write( "\"Team scored 78\" then translates as
\n" ); document.write( " $\"19%2B2%2827-y%29%2B3y=78\"$ ,
\n" ); document.write( "and that equation can be solved for $\"y\"$ as shown above.
\n" ); document.write( "
\n" ); document.write( "OTHER WAYS: There are other ways to solve the system of equations,
\n" ); document.write( "but the result is the same:
\n" ); document.write( "there were $\"highlight%285%29\"$ 3-point shots,
\n" ); document.write( "and $\"highlight%2822%29\"$ 2-point shots. \n" ); document.write( "

\n" );
