It would be 5 months until the price for the notebook computer would be the same. Here are the steps to solving the problem:

1. Step up the equation, 200 + 10x = 100 + 30x
2. Subtract 100 from both sides and Subtract 10 from both sides,
100 - 200 =  10x + 30x, 100 = 20x
3. Solve for x, 100/20 = 20x/20, x= 5
