Problema Solution
John studied twice as long for a history exam as he did for an English exam. If he studied 6 hours in all, how long did he study for each exam?

Time for english exam = x
=> Time for history exam = 2x
Total time studied = 6 hours
=> x + 2x = 6 => 3x = 6 => x = 2
=> He studied 2 hours for english and 4 hours for History exam
