Algebra.Com's Answer #457257 by timvanswearingen(106)![]() ![]() You can put this solution on YOUR website! Multiply the second equation by 3, the result is:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now line up this equation and the first equation and add them up by adding like terms, the result will be:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide both sides by 17:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now plug in 3 for s, in any equation used in the problem. I'll use the first equation:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Subtract 15:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide by 9:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
