What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have expressions:

= (3.1a – 2.7b) + (1.5a – 4.9b)

= 4.6a - 7.6b

= (2.3a + 0.2b) – 8b

= 2.3a - 7.8b

= (–3.5b + a) – (4.1b – 3.6a)

= 4.6a - 7.6b

–0.4b + (8b + 4.6a)

= 4.6a + 7.6b

= 4.6a – 7.6b

Thus, the expressions first, second, and fifth are equivalent after simplifying.
