Решить уравнение: |m|−7+8=7 спам бан​

Answer 1

Ответ:

|м|=7+7-8

|м|=6

м=-6;6

Answer 2

Solving the Equation: |m| - 7 + 8 = 7

To solve the equation |m| - 7 + 8 = 7, we need to isolate the variable m. Let's break down the steps:

1. Start by simplifying the equation: - |m| - 7 + 8 = 7 - |m| + 1 = 7

2. Next, subtract 1 from both sides of the equation to isolate the absolute value term: - |m| = 7 - 1 - |m| = 6

3. Since the absolute value of a number can be positive or negative, we need to consider both cases:

Case 1: m is positive: - If m is positive, then |m| = m. Therefore, we have: - m = 6

Case 2: m is negative: - If m is negative, then |m| = -m. Therefore, we have: - -m = 6

4. To solve for m in the second case, we need to multiply both sides of the equation by -1: - -1 * -m = -1 * 6 - m = -6

Therefore, the solutions to the equation |m| - 7 + 8 = 7 are m = 6 and m = -6.
