2x + 2x + 2 = 4x + 2

Lets start with 5 and then 8 for x

2 (5) = 10 + 2 (5) = 10 = 20

20+2 = 22

now the second

4 (5) = 20+2 = 2

true

8

2 (8) = 16 + 2 (8) = 16 = 32 + 2 = 34

second

4 (8) = 32 + 2 = 34

this statement is always true.

all solutions.

Simple ...

you have:

2x+2x+2=4x+2

4x+2=4x+2

We can immediately see 2=2

True.

Thus, your answer.
