Question

12 = (7x – 9) – (11 – x)

Answer 1

12 = (7x – 9) – (11 – x)

12 = 7х - 9 - 11 + х

7х - 9 -11 + х = 12

8х = 12 +9 +11

8х = 32 I : 8

х = 4

Answer 2

Let's solve the equation step by step:

Given equation: 12 = (7x – 9) – (11 – x)

Distribute the negative sign on the right side: 12 = 7x - 9 - 11 + x

Combine like terms: 12 = 8x - 20

Add 20 to both sides to isolate the term with 'x': 32 = 8x

Now, divide both sides by 8 to solve for 'x': x = 32 / 8 x = 4

So, the solution to the equation is x = 4.
