Answer:
[tex]x \in \mathbb \: R[/tex]
Step-by-step explanation:
The given equation is:
[tex] - (2x + 2) - 1 = - x - (x + 3)[/tex]
We expand to get:
[tex] - 2x - 2 - 1 = - x - x - 3[/tex]
We group like terms to get:
[tex] - 2x + x + x = - 3 + 1 + 2[/tex]
We combine the like terms to obtain:
[tex] - 2x + 2x = - 3 + 3[/tex]
[tex] 0 = 0[/tex]
This is always true therefore the solution is infinite.
