Algebra.Com's Answer #7656 by elima(1433) ![]() You can put this solution on YOUR website! First of all lets make x=the number; \n" ); document.write( "Now we know twice that number increased(+) by 3; \n" ); document.write( "2x+3; \n" ); document.write( "The result is(=); \n" ); document.write( "8 lease(-) than 3 times that number; \n" ); document.write( "3x-8; \n" ); document.write( "So we have; \n" ); document.write( "2x+3=3x-8 \n" ); document.write( "Subtract 3 from both sides; \n" ); document.write( "2x+3-3=3x-8-3 \n" ); document.write( "2x=3x-11 \n" ); document.write( "Now subtract 3x from both sides; \n" ); document.write( "2x-3x=3x-11-3x; \n" ); document.write( "-x=-11 \n" ); document.write( "We do not want to leave the answer with -x so we will divide each side by -1; \n" ); document.write( "x=11 \n" ); document.write( "Hope you understand \n" ); document.write( "=) \n" ); document.write( " |
