You add the like terms to get #2X+30#.

Explanation:

In simplifying algebraic expressions, you group the like terms and then combine them according to the mathematical signs that precede them.

In this example, since all the signs are ones of addition, and the like terms are already grouped, you simply add the terms.

#X+X+15+15#

  • #X+X=2X#
  • #15+15=30#

#:.2X+30#
