Algebra.Com's Answer #676778 by addingup(3677)![]() ![]() You can put this solution on YOUR website! 2s+2p = 42 (1) \n" ); document.write( "3s+p = 37 (2) \n" ); document.write( "-------------------- \n" ); document.write( "How much are the pant? \n" ); document.write( "In equation (1), multiply all times 3 \n" ); document.write( "In equation (2{, multiply all times 2 and subtract from (1): \n" ); document.write( "6s+6p = 126 \n" ); document.write( "- \n" ); document.write( "6s+2p = 74 \n" ); document.write( "---------- \n" ); document.write( "0s+4p = 52 so now we have zero shirts. Divide both sides by 4 and you get: \n" ); document.write( "p = 13 the pants are 13. And Annette bought 1 pair, and she spent 37. Now, 37-13 = 24 so she paid 24 for 3 shirts or 8 each \n" ); document.write( "Pants cost: 13 \n" ); document.write( "Shirts cost: 8 \n" ); document.write( "------------------ \n" ); document.write( "Check with Suzy: \n" ); document.write( "2 shirts at 8 = 16 \n" ); document.write( "2 pants at 13 = 26 \n" ); document.write( "Total... . .. .42 Correct, this is how much she spent. \n" ); document.write( " |
