Precious · Answer 1

Samantha is correct

Step-by-step explanation:

4 (2) + 2 = 10

2 + 17 + 3 (2) - 15 = 10

both are equal to 10 and are therefore equivalent expressions.

Jerome Simmons · Answer 2

Samantha is correct because when using x = 2, the resulting values in both expressions are equal.

Step-by-step explanation:

x + 17 + 3x - 15

Collecting terms gives

x + 3x + 17 - 15 = 4x + 2.
