Ok so let May be \"y\" and Mylene be \"x\" \n" ); document.write( "It says that may is 3 less than twice mylene so: \n" ); document.write( "y = 2x - 3 \n" ); document.write( "Now it says that the sum of their ages is 51 so: \n" ); document.write( "x + y = 51\r \n" ); document.write( "\n" ); document.write( "Now we can substitute \"y\" with \"2x- 3\" in the equation above: \n" ); document.write( "x + y = 51 \n" ); document.write( "x + 2x - 3 = 51 \n" ); document.write( "Now we have to take like terms to the same side: \n" ); document.write( "x + 2x = 51 + 3 \n" ); document.write( "3x = 54 \n" ); document.write( "x = 18 \n" ); document.write( "Now we have \"x = 18\" we also knew that \"y = 2x - 3 \" \n" ); document.write( "So: \n" ); document.write( "y = 2(18) - 3 \n" ); document.write( "y= 33\r \n" ); document.write( "\n" ); document.write( "May is 33 years old and Mylene is 18 years old. \n" ); document.write( "Check: \n" ); document.write( "x + y = 51 \n" ); document.write( "18 + 33 = 51 \n" ); document.write( " |
