Answer 2

Ответа 2:
-3
+3
потому что |х| может быть как (х) так и (-х)

Answer 3

To solve the equation |x| - 6 = -9, we'll need to consider two cases: one where x is positive (x ≥ 0) and one where x is negative (x < 0). Let's solve it step by step:

Case 1: x ≥ 0 In this case, |x| is equal to x. Therefore, we can rewrite the equation as x - 6 = -9. Now, let's solve for x: x - 6 = -9 Add 6 to both sides: x - 6 + 6 = -9 + 6 x = -3

So, for x ≥ 0, the solution is x = -3.

Case 2: x < 0 In this case, |x| is equal to -x (since x is negative). Therefore, we can rewrite the equation as -x - 6 = -9. Now, let's solve for x: -x - 6 = -9 Add 6 to both sides: -x - 6 + 6 = -9 + 6 -x = -3 Multiply both sides by -1 to isolate x: x = 3

So, for x < 0, the solution is x = 3.

Therefore, the complete solution to the equation |x| - 6 = -9 is x = -3 and x = 3.
