Question

Решите уравнение ||x|-4|=5

Answer 1

$| |x| - 4 | = 5 \\ \\ |x| - 4 = 5 \\ |x| - 4 = - 5 \\ \\ x = 9 \\ x = - 9 \\ x = \ - \\ \\ x1 = 9 \\ x2 = - 9$

Answer 2

I can help you solve the equation |x-4|=5 in Russian. Here are the steps:

1. To solve an absolute value equation, we need to find the values of x that make the expression inside the absolute value equal to 5 or -5. That is, we need to solve two equations: x-4=5 and x-4=-5. 2. To solve x-4=5, we add 4 to both sides and get x=9. This is one solution of the original equation. 3. To solve x-4=-5, we add 4 to both sides and get x=-1. This is another solution of the original equation. 4. Therefore, the final answer is x=9 or x=-1. We can check these solutions by plugging them into the original equation and verifying that they satisfy it.
