If you have the expression 5x + 2y - 3x + 4y, how would you simplify it?

Back

First, group the like terms: (5x - 3x) + (2y + 4y) = 2x + 6y.

In the expression 4k + 6k - 3k + 3s - s, what are the combined like terms?

Back

The combined like terms are 4k + 6k - 3k = 7k and 3s - s = 2s, resulting in 7k + 2s.
