Let Johns age = x \n" ); document.write( "Since matt is 4 times him minus 3 let his age = 4x-3\r \n" ); document.write( "\n" ); document.write( "Total age =52\r \n" ); document.write( "\n" ); document.write( "Form an equation\r \n" ); document.write( "\n" ); document.write( "x+4x-3=52\r \n" ); document.write( "\n" ); document.write( "Collect like terms\r \n" ); document.write( "\n" ); document.write( "5x-3=52\r \n" ); document.write( "\n" ); document.write( "Get 5x on its own by adding 3 to both sides\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "5x=55\r \n" ); document.write( "\n" ); document.write( "Divide both sides by 5 to solve for x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x=11 (Johns age is 11)\r \n" ); document.write( "\n" ); document.write( "To find Matts age times 4 by x (johns age)then minus 3= 44-3=41 \n" ); document.write( "So Johns age is 11 and Matts age is 41 \n" ); document.write( " |
