1

Understand the problem

−2+4a+4−2a+3−2a= -2+4a+4-2a+3-2a=

2

Step-by-step solution

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

First, we solve the addition exercise:

4+3=7 4+3=7

We now obtain the exercise:

−2+7+4a−2a−2a= -2+7+4a-2a-2a=

We add the coefficients a:

4a−2a=2a 4a-2a=2a

2a−2a=0 2a-2a=0

We now obtain the exercise:

−2+7+0= -2+7+0=

We use the substitutive property:

7−2+0=5+0=5 7-2+0=5+0=5
