Question

Problem Combine the like terms to create an equivalent expression: − 5 r + 8 r + 5

Answer 1

Answer: -5r+8r+5=3r+5

Explanation:

First add like terms, so -5r and 8r. For a second lets pretend the r doesn't exist. So, what is -5 + 8, 3, so 3r. Since 3r and 5 cannot be combined, the equivalent expression is 3r+5.
