Answer 2

Ответ:

x=2

x = -6

Пошаговое объяснение:

При решение с модулем будет два ответа

|2x+4|=8

2x+4=8

2x = 8-4

2x=4

x=2

|2x+4|=8

2x+4= - 8

2x = -8 - 4

2x= -12

x = -6

Answer 3

Solving the Equation |2x+4|=8

To solve the equation |2x+4|=8, we need to consider both the positive and negative cases for the absolute value expression.

Positive Case: When |2x+4| equals 8, the expression inside the absolute value can be either 8 or -8.

1. For 2x+4=8: - Subtracting 4 from both sides gives 2x=4. - Dividing both sides by 2 gives x=2.

2. For 2x+4=-8: - Subtracting 4 from both sides gives 2x=-12. - Dividing both sides by 2 gives x=-6.

Negative Case: When |2x+4| equals -8, there are no solutions because an absolute value cannot be negative.

Therefore, the solutions to the equation |2x+4|=8 are x=2 and x=-6.
