Question

Z-1/3=-7/12 решения уравнения

Answer 1

Ответ:

Пошаговое объяснение:

z - 1/3 = -7/12

z = -7/12 + 1/3

z = -7/12 + 4/12

z = -3/12

z = -1/4

Answer 2

Ответ: х=-1/4

Пошаговое объяснение:

х-1/3=-7/12

х=-7/12+1/3=(-7+4)/12=-3/12

х=-1/4

Answer 3

To solve the equation Z - 1/3 = -7/12, we can isolate the variable Z by performing inverse operations.

First, let's get rid of the fraction 1/3 by multiplying both sides of the equation by 3:

3 * (Z - 1/3) = 3 * (-7/12)

This simplifies to:

3Z - 1 = -21/12

Next, we can eliminate the fraction -21/12 by multiplying both sides of the equation by 12:

12 * (3Z - 1) = 12 * (-21/12)

This simplifies to:

36Z - 12 = -21

Now, let's isolate the variable Z by adding 12 to both sides of the equation:

36Z - 12 + 12 = -21 + 12

This simplifies to:

36Z = -9

Finally, we can solve for Z by dividing both sides of the equation by 36:

(36Z) / 36 = (-9) / 36

This simplifies to:

Z = -9/36

Simplifying the fraction, we get:

Z = -1/4

Therefore, the solution to the equation Z - 1/3 = -7/12 is Z = -1/4.
