greg is 2 years older than liam.
\n" ); document.write( "greg is celebrating his 9th birthday.
\n" ); document.write( "how old would both boys be after 3, 7, 10 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when greg is 9, liam is 7
\n" ); document.write( "in 3 years, greg will be 12 and liam will be 10.
\n" ); document.write( "in 7 years, greg will be 16 and liam will be 14.
\n" ); document.write( "in 10 years, greg will be 19 and liam will be 17.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to make an equation out of this, let x = liam's age and let y = greg's age.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since greg is 2 years older than liam, you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = x + 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x represents liam's age and y represents greg's age.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when x = 7, y = 9
\n" ); document.write( "when x = 7 + 3 = 10, y = 12
\n" ); document.write( "when x = 7 + 7 = 14, y = 16
\n" ); document.write( "when x = 7 + 10 = 17, y = 19\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the equation can be graphed as shown below:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
