**MsP**, Friday, December 28, 2007 at 8:08amDon't be scared by word problems...just take what you know and plug it into an equation.

Twice as long for history as psych, so psych will be X and history will be 2X. You know the total is 12 hours, therefore the equation will be 2X + X = 12.

Combine like terms...3X = 12.

So X = 4 (psych) and 2X = 8 (history)
