Alex is 8 years younger than his sister.
\n" ); document.write( "His mother is 6 years more than twice of his sister’s age.
\n" ); document.write( "His mother is 42 years old.
\n" ); document.write( "Find the ages of Alex and his sister.
\n" ); document.write( ":
\n" ); document.write( "Let a = Alex's present age
\n" ); document.write( "Let s = sister's present age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( "\"Alex is 8 years younger than his sister.\"
\n" ); document.write( "a = s-8
\n" ); document.write( ":
\n" ); document.write( "\"His mother is 6 years more than twice of his sister’s age. His mother is 42 years old.\"
\n" ); document.write( "2s + 6 = 42
\n" ); document.write( "2s = 42 - 6
\n" ); document.write( "2s = 36
\n" ); document.write( "s = \"36%2F2\"
\n" ); document.write( "s = 18 is the sisters age
\n" ); document.write( ":
\n" ); document.write( "I'll let you find Alex's age
