Algebra.Com's Answer #6620 by usyim88hk(158)![]() ![]() ![]() You can put this solution on YOUR website! We can set up equations to find out what the answer is \n" ); document.write( "Let x be the number of small T-shirts the gift shop ordered \n" ); document.write( "So 2x is equal to the number of medium T-shirts \n" ); document.write( "And 3x is equal to the number of large T-shirts \n" ); document.write( "Now we know that there are 42 T-shirts in total, so \n" ); document.write( "x+2x+3x = 42 \n" ); document.write( "now we can add the xs up \n" ); document.write( "6x=42 \n" ); document.write( "Then divide both sides by 6 \n" ); document.write( "x=7 \n" ); document.write( "So the number of small T-shirts is 7 \n" ); document.write( "the number of medium T-shirts is 14 \n" ); document.write( "and the number of large T-shirts is 21 \n" ); document.write( " |
