What is the main difference between simplifying and solving? Which one gives you a value for a variable? How do you know the difference?

when you simplify you continue until you get to the simplest form but when you solve you continue until you get an answer. Solving gives you a value for a variable. You mean simplify and get 2x - 10 but when you solve you continue until you get x as 5

Step-by-step explanation:

11 + x

Step-by-step explanation:

Let's write out each of the answer choices:

A) 11x

B) 11 + x

C) 11 minus x  ⇒  11 - x

D) Negative x + 11  ⇒  -x + 11

Examine each of them. Clearly, A and D aren't the same (A is multiplication, not addition, and D has a negative x instead of a positive x). C is actually the same as D, if you switch the places of 11 and -x: 11 - x = -x = 11.

Finally, answer choice B is correct because by the Commutative Property of Addition, 11 + x = x + 11.

Hope this helps!
