Answer 2

Ответ:

х=40

Пошаговое объяснение:

4х-5=155

4х=155+5

4х=160

х=160:4

х=40

Answer 3

To solve the equation |4x - 5| = 155, we need to consider two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: 4x - 5 is positive In this case, the equation becomes 4x - 5 = 155. To solve for x, we can add 5 to both sides of the equation and then divide by 4: 4x - 5 + 5 = 155 + 5 4x = 160 x = 40

Case 2: 4x - 5 is negative In this case, the equation becomes -(4x - 5) = 155. To solve for x, we can multiply both sides of the equation by -1 to remove the negative sign: -1(4x - 5) = -1(155) -4x + 5 = -155 -4x = -160 x = 40

Therefore, the equation |4x - 5| = 155 has two solutions: x = 40 in both cases.
