Bill has 12 hours available to study for his final exams in history and psychology. He decides that he needs to spend twice as much time studying for history as for psychology. How long should he study

How would I even begin to solve this...I am not good with word problems. Thank you

okay, i dont know how you would set this up, but he needs to spend 8 hours on history and 4 hours on psychology. 8+4 equals 12!

Don'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)
