Write an equation for each statement.
\n" ); document.write( ":
\n" ); document.write( "\"the sum of the ages of Ira and Sofia is 26.
\n" ); document.write( " I + S = 26
\n" ); document.write( "or
\n" ); document.write( "I = (26-S)
\n" ); document.write( ":
\n" ); document.write( "\" the difference between 4 times Sofia's age and twice Ira's age is 8.\"
\n" ); document.write( "4S - 2I = 8
\n" ); document.write( ";
\n" ); document.write( "Substitute (26-S) for I in the above equation, find S;
\n" ); document.write( "4S - 2(26-S) = 8
\n" ); document.write( "4S - 52 + 2S = 8
\n" ); document.write( "4S + 2S = 8 + 52
\n" ); document.write( "6S = 60
\n" ); document.write( "S = 10
\n" ); document.write( "Then
\n" ); document.write( "I = 26 - 10
\n" ); document.write( "I = 16
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution using the statement:
\n" ); document.write( "\"the difference between 4 times Sofia's age and twice Ira's age is 8.\"
\n" ); document.write( "4(10) - 2(16) = 8 \n" ); document.write( "
\n" );
