Объяснение:

14х-(-x-1)+(2х+6)

14х+x+1+2х+6

17x+1+6

17x+7

Answer 2

Let's simplify the given expression step by step:

1. Distribute the negative sign in front of the parentheses: 14x - (-x - 1) + (2x + 6)

   This becomes: 14x + x + 1 + 2x + 6

2. Combine like terms (terms with the same variable raised to the same power): (14x + x + 2x) + (1 + 6)

   Simplifying further: 17x + 7

So, the correct simplified form of the expression is: 17x + 7

Among the given options, the expression matches option (б) 17x + 7.
