\n" ); document.write( "Carefully convert the given information into algebraic expressions.

\n" ); document.write( "The number you are looking for is her brother's age; let that be the variable x.
\n" ); document.write( "x = brother's age

\n" ); document.write( "\"the sum of her brother's age and 6\": x+6

\n" ); document.write( "\"half the sum of her brother's age and 6\": (x+6)/2

\n" ); document.write( "Her age (9) is half the sum of her brother's age and 6:

\n" ); document.write( "\"9+=+%28x%2B6%29%2F2\"

\n" ); document.write( "Solve using basic algebra.
