Mrs. Shieh was 24 years old when Ingred was born. In three years the sum of their ages will be 68 years. How old is each now?
\n" ); document.write( ":
\n" ); document.write( "We can say that S is 24 yrs older than I, therefore
\n" ); document.write( "S = (I+24)
\n" ); document.write( ":
\n" ); document.write( "An equation for the statement:
\n" ); document.write( "\"In three years the sum of their ages will be 68 years.\"
\n" ); document.write( "(S+3) + (I+3) = 68
\n" ); document.write( "S + I + 6 = 68
\n" ); document.write( "S + I = 68-6
\n" ); document.write( "S + I = 62
\n" ); document.write( ":
\n" ); document.write( " How old is each now?
\n" ); document.write( ":
\n" ); document.write( "Substitute (I+24) for S in the above equation
\n" ); document.write( "(I+24) + I = 62
\n" ); document.write( "2I = 62 - 24
\n" ); document.write( "I = \"38%2F2\"
\n" ); document.write( "I = 19 yrs
\n" ); document.write( "then
\n" ); document.write( "19+24 = 43 yrs is S
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement:
\n" ); document.write( "\"In three years the sum of their ages will be 68 years.\"
\n" ); document.write( "(43+3) + (19+3) = 68 \n" ); document.write( "
\n" );
