00:00 Solve

00:03 We'll use the commutative law and arrange the exercise to make it easier to solve

00:13 We'll group terms according to the associative law

00:35 And this is the solution to the question

We can use the substitutive property and arrange the exercise in a way that makes solving the exercise simpler:

$-2+4+3+4a-2a-2a=$

First, we solve the addition exercise:

$4+3=7$

We now obtain the exercise:

$-2+7+4a-2a-2a=$

We add the coefficients a:

$4a-2a=2a$

$2a-2a=0$

We now obtain the exercise:

$-2+7+0=$

We use the substitutive property:

$7-2+0=5+0=5$

$5$
