1. 1

   4x - 2x + 3 + 7

   Put variable terms together and constants together. Reordering addition does not change the value.

2. 2

   (4 - 2)x + (3 + 7)

   The x-terms share the same variable, so combine their coefficients; then add the constants.

3. 3

   2x + 10

   Subtract 2 from 4 and add 3 and 7 to finish simplifying.
