Algebra.Com's Answer #676152 by LynnMomo(10)![]() ![]() You can put this solution on YOUR website! Let x be amount of money Thomas started with.\r \n" ); document.write( "\n" ); document.write( "First store: $ (x/2 +8) \n" ); document.write( "Second store:$ {[x-(x/2 +8)]/2 +8}\r \n" ); document.write( "\n" ); document.write( "If he had $7 left: \n" ); document.write( "X- first store-second store= $7 \n" ); document.write( "X- (x/2+8)- [x-(x/2 +8)]/2 +8= 7 \n" ); document.write( "X-x/2-8-[(x-x/2-8)/2+8]=7 \n" ); document.write( "X-x/2-8-(x-x/2-8)/2-8=7 \n" ); document.write( "X/2-8-(x/2-8)/2-8=7 \n" ); document.write( "X/2-(x/2-8)/2-8-8=7 \n" ); document.write( "X/2-(x/2-8)/2-16=7 \n" ); document.write( "(X-x/2+8)/2=23 \n" ); document.write( "X-x/2+8=46 \n" ); document.write( "X-x/2=46-8 \n" ); document.write( "X-x/2=38 \n" ); document.write( "X/2=38 \n" ); document.write( "X=76 \n" ); document.write( "$76 is the amount of dollars he started with.\r \n" ); document.write( "\n" ); document.write( "I hope my solution help you in Math.^^\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
