Algebra.Com's Answer #831822 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Yes, I can.... \n" ); document.write( "But that's probably not what you meant. \n" ); document.write( "The term \"11y\" is in both of the given equations. So \n" ); document.write( "7x+11y=188 --> 11y=188-7x \n" ); document.write( "13x+11y=236 --> 11y=236-13x \n" ); document.write( "Then, by substitution, \n" ); document.write( "188-7x=236-13x \n" ); document.write( "From there, solve using basic algebra. \n" ); document.write( " \n" ); document.write( " |
