The Mainers won 24 more than twice as many games as they lost. They played 162 regular season games. How many wins and losses did the mariners have? \n" ); document.write( "
Algebra.Com's Answer #53006 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Let the number of games that the Mariners won be represented by W and the number of games that \n" ); document.write( "they lost be represented by L. The total of their wins and losses equals the 162 games that they \n" ); document.write( "played. In equation form you can write: \n" ); document.write( ". \n" ); document.write( "W + L = 162 \n" ); document.write( ". \n" ); document.write( "The tricky part to this problem is to translate \"won 24 more than twice as many games as they lost\" \n" ); document.write( "into a math equation. If you think \"wins minus 24\" then that must be 2 times the number of \n" ); document.write( "games they lost. In equation form this translation can be written: \n" ); document.write( ". \n" ); document.write( "W - 24 = 2*L \n" ); document.write( ". \n" ); document.write( "Let's solve our first equation for L by subtracting W from both sides to get: \n" ); document.write( ". \n" ); document.write( "L = 162 - W \n" ); document.write( ". \n" ); document.write( "Then substitute this value (the right side) for L in our second equation to get: \n" ); document.write( ". \n" ); document.write( "W - 24 = 2*(162 - W) \n" ); document.write( ". \n" ); document.write( "Multiplying out the right side results in: \n" ); document.write( ". \n" ); document.write( "W - 24 = 324 - 2W \n" ); document.write( ". \n" ); document.write( "Eliminate the - 2W on the right side by adding 2W to both sides to get: \n" ); document.write( ". \n" ); document.write( "3W - 24 = 324 \n" ); document.write( ". \n" ); document.write( "Eliminate the -24 on the left side by adding 24 to both sides: \n" ); document.write( ". \n" ); document.write( "3W = 348 \n" ); document.write( ". \n" ); document.write( "Finally, find the number of wins the Mariners had by dividing both sides by 3 and you \n" ); document.write( "have W = 348/3 = 116 \n" ); document.write( ". \n" ); document.write( "This says the Mariners won 116 of their 162 games. Therefore, they lost 162 - 116 = 46 games. \n" ); document.write( ". \n" ); document.write( "Notice that if we doubled their 46 games and added 24 more games the total would be 92 + 24 = 116, the \n" ); document.write( "number of games they won. That works! \n" ); document.write( ". \n" ); document.write( "Now lets go back to when we solved the first equation for L and put it into the second. We could \n" ); document.write( "also have solved the first equation for W to get W = 162 - L and substituted the right side \n" ); document.write( "of that for W in the second equation. It would have worked out the same except that we would \n" ); document.write( "have found that L = 46 games and then would have to solve for W by subtracting 46 from 162. \n" ); document.write( "So you could have done it either way. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem better. \n" ); document.write( " \n" ); document.write( " |
