FIVE YEARS AGO GEMMA WAS TWICE AS OLD AS TONY IS NOW,
\n" ); document.write( "IN SEVEN YEARS SHE WILL BE FIVE TIMES AS OLD TONY IS NOW
\n" ); document.write( " WHAT ARE THEIR CURRENT AGES?
\n" ); document.write( ":
\n" ); document.write( "let g = G's present age
\n" ); document.write( "let t = T's present age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"FIVE YEARS AGO GEMMA WAS TWICE AS OLD AS TONY IS NOW,\"
\n" ); document.write( "g - 5 = 2t
\n" ); document.write( "g = 2t + 5
\n" ); document.write( ":
\n" ); document.write( "\"IN SEVEN YEARS SHE WILL BE FIVE TIMES AS OLD TONY IS NOW\"
\n" ); document.write( "g + 7 = 5t
\n" ); document.write( "Replace g with (2t+5)
\n" ); document.write( "(2t + 5) + 7 = 5t
\n" ); document.write( "2t + 12 = 5t
\n" ); document.write( "12 = 5t - 2t
\n" ); document.write( "12 = 3t
\n" ); document.write( "t = \"12%2F3\"
\n" ); document.write( "t = 4 yrs is T's present age
\n" ); document.write( "then
\n" ); document.write( "g = 2(4) + 5
\n" ); document.write( "g = 13 yrs is G's present age
