WHEN MR. LOWE RETURN FROM HIS FISHING TRIP, HIS STUDENTS INQUIRED AS TO THE LENGTH OF HIS PRIZE CATCH.
MR. LOWE ANSWERED.
"THE HEAD MEASURED 9 INCHES."
"THE TAIL WAS AS LONG AS THE HEAD AND HALF THE BODY."
THE BODY WAS AS LONG AS THE HEAD AND TAIL." HOW LONG WAS MR. LOWE'S PRIZE FISH?

Do not use all caps. It is rude, like SHOUTING online, and also more difficult to read. Thank you.
H = 9
T = 9 + .5B
B = 9 + T
Substitute 9 + .5B for T in the last equation to solve for B. Put that value in the previous equation to find T.
Add H + B + T.
