Answer 2

Answer:

ANSWERS ARE IN FOLLOWING:-

Step-by-step explanation:

1) A variable is something whose value can change. (True)

2)Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) (True)

3)False

4)-2

5)simplify is to make simpler,reducing to component parts, or making easier to understand while solve is to find an answer or solution to a problem or question. (False)

6)-3

7)A constant is something whose value does not change.(True)

8)3xy + 2a + 3b

9)True

10)Infinite (unlimited) solutions
