You can put this solution on YOUR website!
A construction company spent 26 hours on two jobs.
\n" ); document.write( " One job took 5 more the twice the number of hours of the other.
\n" ); document.write( " How long did the larger job take?
\n" ); document.write( ":
\n" ); document.write( "Let x = time for larger job
\n" ); document.write( "Let y = time for the other job
\n" ); document.write( ":
\n" ); document.write( "\"A construction company spent 26 hours on two jobs.\"
\n" ); document.write( "x + y = 26
\n" ); document.write( "y = (26-x); this form for substitution
\n" ); document.write( ":
\n" ); document.write( "\"One job took 5 more the twice the number of hours of the other.\"
\n" ); document.write( "x = 2y + 5
\n" ); document.write( ":
\n" ); document.write( " How long did the larger job take?
\n" ); document.write( "Replace y with (26-x) in the above equation
\n" ); document.write( "x = 2(26-x) + 5
\n" ); document.write( "x = 52 - 2x + 5
\n" ); document.write( "x + 2x = 52 + 5
\n" ); document.write( "3x = 57
\n" ); document.write( "x = \"57%2F3\"
\n" ); document.write( "x = 19 hrs
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution; y = 26-19 = 7 hrs
\n" ); document.write( "\"One job took 5 more the twice the number of hours of the other.\"
\n" ); document.write( "19 = 2(7) + 5
\n" ); document.write( "
\n" );
