Answer 2

Let's simplify the expression step by step:

1. Start with the innermost parentheses:

   • Inside the parentheses (1-х) simplifies to (1 - x).

2. Now, simplify the expression within the next set of parentheses:

   • Inside the parentheses (3x - 4(1 - x)) simplifies to (3x - 4 + 4x) since you distribute the -4 across both terms inside the parentheses.
   • This further simplifies to (7x - 4).

3. Next, simplify the expression within the parentheses (9 + 8):

   • Inside the parentheses (9 + 8) simplifies to 17.

4. Now, we can substitute these simplified expressions back into the original equation: 10x - (6x - 2(7x - 4) - 17) = 27.

5. Distribute the -2 across the terms inside its parentheses: 10x - (6x - 14x + 8 - 17) = 27.

6. Combine like terms inside the parentheses: 10x - (-8x - 9) = 27.

7. Distribute the negative sign across the terms inside the parentheses: 10x + 8x + 9 = 27.

8. Combine like terms on the left side of the equation: 18x + 9 = 27.

9. Now, isolate x by moving 9 to the other side of the equation by subtracting 9 from both sides: 18x = 27 - 9, 18x = 18.

10. Finally, divide both sides by 18 to solve for x: x = 18 / 18, x = 1.

So, the solution to the equation is x = 1.
