A Basketball team scored 87 points in 2 point and 3 point baskets. If the 2 point baskets had been 3 point baskets, and the 3 point baskets had been 2 points, the team would have scored 93 points. Find how many 2 point baskets and how many 3 point baskets the team scored.
\n" ); document.write( ".
\n" ); document.write( "Let x = number of 2-point baskets
\n" ); document.write( "and y = number of 3-point baskets
\n" ); document.write( ".
\n" ); document.write( "Because we have two unknowns, we need to find two equations:
\n" ); document.write( ".
\n" ); document.write( "From: \"A Basketball team scored 87 points in 2 point and 3 point baskets.\" we get:
\n" ); document.write( "2x + 3y = 87 (equation 1)
\n" ); document.write( ".
\n" ); document.write( "And from: \"If the 2 point baskets had been 3 point baskets, and the 3 point baskets had been 2 points, the team would have scored 93 points\" we get:
\n" ); document.write( "2y + 3x = 93 (equation 2)
\n" ); document.write( ".
\n" ); document.write( "solve equation 1 for y:
\n" ); document.write( "2x + 3y = 87
\n" ); document.write( "3y = 87-2x
\n" ); document.write( "y = 29-(2/3)x
\n" ); document.write( ".
\n" ); document.write( "substitute above into equation 2 to solve for x:
\n" ); document.write( "2y + 3x = 93
\n" ); document.write( "2(29-(2/3)x) + 3x = 93
\n" ); document.write( "58-(4/3)x + 3x = 93
\n" ); document.write( "-(4/3)x + 3x = 35
\n" ); document.write( "-4x + 9x = 105
\n" ); document.write( "5x = 105
\n" ); document.write( "x = 21 (number of 2-point baskets)
\n" ); document.write( ".
\n" ); document.write( "To find number of 3-point baskets, substitute back into equation 1:
\n" ); document.write( "2x + 3y = 87
\n" ); document.write( "2(21) + 3y = 87
\n" ); document.write( "42 + 3y = 87
\n" ); document.write( "3y = 45
\n" ); document.write( "y = 15\r
