James has a total of 25 screwdrivers in his toolbox. Some are Phillips (xx) and some are flatheads (yy). The amount of flatheads (yy) he has is 1 more than the amount of Phillips. Write two equations that represent this situation. Use xx for Phillips and yy for flatheads.

The equation that represents that the total is 25:

The equation that represents that the number of flatheads he has

1 answer

Let's define the variables as follows:

  • Let \( xx \) represent the number of Phillips screwdrivers.
  • Let \( yy \) represent the number of flathead screwdrivers.

According to the problem, we can form the following two equations:

  1. The total number of screwdrivers is 25: \[ xx + yy = 25 \]

  2. The number of flatheads is 1 more than the number of Phillips: \[ yy = xx + 1 \]

These equations will help you in solving the problem in the next step!
