X + (x + 10) +2 (x + 10) зз0

It seems like you are trying to solve an algebraic equation. However, there is a small typo in your equation, as "зз0" doesn't make sense in this context. It looks like it might have been a misprint or mistranslation for an equals sign ("=") or another number.

If you meant "x + (x + 10) + 2(x + 10) = 0," then the equation can be worked out as follows:

Let's distribute and combine like terms: x + (x + 10) + 2(x + 10) = 0 x + x + 10 + 2x + 20 = 0

Combine all the x terms: 4x + 30 = 0

Subtract 30 from both sides: 4x + 30 - 30 = 0 - 30 4x = -30

Now divide both sides by 4 to solve for x: 4x / 4 = -30 / 4 x = -7.5

So the solution to the equation is x = -7.5. If the original equation you provided was not actually "x + (x + 10) + 2(x + 10) = 0", please provide the correct equation so that I can assist you further.
