1. Problem Description

We are given the equation x+6=2x|x+6| = 2x and a partially completed solution. We need to fill in the blanks numbered from 32 to 39 with the appropriate values or symbols from the provided options.

2. Solution Steps

(i) Case 1: x+60x+6 \ge 0. This means x6x \ge -6. So, 32-1 should be gege. Therefore, 32 is "シ" (\ge). Equation (1) is x6x \ge -6.
When x+60x+6 \ge 0, x+6=x+6|x+6| = x+6. Thus, x+6=2xx+6 = 2x. So, 33 is x+6x+6.
Then, solving x+6=2xx+6 = 2x, we get x=6x=6. Thus, 34 is
6.
Equation (2) is x=6x=6.
Now, we check if x=6x=6 satisfies the condition x6x \ge -6. Since 666 \ge -6, the condition is satisfied.
(ii) Case 2: x+6<0x+6 < 0. This means x<6x < -6. So, 32-2 should be <<. Therefore, 32 is "ケ" (<<). Equation (3) is x<6x < -6.
When x+6<0x+6 < 0, x+6=(x+6)=x6|x+6| = -(x+6) = -x-6. Thus, x6=2x-x-6 = 2x. So, 36 is x6-x-6.
Then, solving x6=2x-x-6 = 2x, we get 3x=63x = -6, so x=2x = -2. Thus, 37 is -
2.
Equation (4) is x=2x=-2.
Now, we check if x=2x=-2 satisfies the condition x<6x < -6. Since 2-2 is not less than 6-6, the condition is not satisfied.
Therefore, the only solution is x=6x=6. Thus, 39 is
6.
Now let's go back to filling in 35 and
3

8. Since we know that the equation $x = 6$ satisfies equation (1) and equation (2), then we should select an option regarding if (1) is satisfied by (2) or not.

Since x=6x=6 is a solution for x6x \ge -6, then equation (2) satisfies equation (1). Thus, 35 is "ウ".
Since x=2x=-2 does *not* satisfy equation (3), then equation (4) does not satisfy equation (3). Thus, 38 is "ク".

3. Final Answer

32: シ
33: ス
34: 6
35: ウ
36: ソ
37: -2
38: ク
39: 6
