You can put this solution on YOUR website!
Let x = Sally's present age
\n" ); document.write( "Let y = Adam's present age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"Sally's age six years older than Adam's.
\n" ); document.write( "x = y+6
\n" ); document.write( ":
\n" ); document.write( "\"Three Times Adams age plus Sally's age is 22.\"
\n" ); document.write( "3y + x = 22
\n" ); document.write( ":
\n" ); document.write( "From the 1st statement, replace x with (y+6), find y
\n" ); document.write( "3y + (y+6) = 22
\n" ); document.write( "3y + y = 22 - 6
\n" ); document.write( "4y = 16
\n" ); document.write( "y = \"16%2F4\"
\n" ); document.write( "y = 4 yrs is Adam's age
\n" ); document.write( "then
\n" ); document.write( "4 + 6 = 10 yrs is Sally's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the statement:
\n" ); document.write( "\"Three Times Adams age plus Sally's age is 22.\"
\n" ); document.write( "3(4) + 10 = 22
\n" ); document.write( "\\r
\n" ); document.write( "
\n" ); document.write( "
