There are a total of 20 lions, tigers, and bears at the local zoo.\r
\n" ); document.write( "\n" ); document.write( " The number of tigers is 2 more than the number of lions.\r
\n" ); document.write( "\n" ); document.write( "Let number of lions be x\r
\n" ); document.write( "\n" ); document.write( "Number of tigers will be x+2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " The number of bears is 3 more than the number of lions. \r
\n" ); document.write( "\n" ); document.write( "The number of bears= x+3\r
\n" ); document.write( "\n" ); document.write( "Add them up. They equal 20\r
\n" ); document.write( "\n" ); document.write( "x+x+2+x+3=20\r
\n" ); document.write( "\n" ); document.write( "3x+5 =20\r
\n" ); document.write( "\n" ); document.write( "subtract 5 from both sides\r
\n" ); document.write( "\n" ); document.write( "3x+5-5= 20-5
\n" ); document.write( "3x=15\r
\n" ); document.write( "\n" ); document.write( "divide by 3\r
\n" ); document.write( "\n" ); document.write( "x=5
\n" ); document.write( " There are 5 lions at the zoo.\r
\n" ); document.write( "
\n" ); document.write( "
