Answer 2

Ответ:

Пошаговое объяснение:

(х+1/2):(-1/3)=3 3/4

x + 1/2 = 3 3/4 * (-1/3)

x + 1/2 = 15/4 *(-1/3)

x + 1/2 = -5/4

x = -5/4 - 1/2

x = -5/4 - 2/4

x = -7/4

x = -1 3/4

Answer 3

To solve the equation (х + 1/2) / (-1/3) = 3 3/4, first convert the mixed number 3 3/4 into an improper fraction.

3 3/4 = (4 * 3 + 3) / 4 = 12/4 + 3/4 = 15/4

Now, your equation is (х + 1/2) / (-1/3) = 15/4. To solve for x, you can cross-multiply and solve for x:

(х + 1/2) / (-1/3) = 15/4

First, simplify the left side by multiplying by the reciprocal of (-1/3), which is -3:

(х + 1/2) * (-3) = 15/4

Now, distribute the -3 on the left side:

-3(x + 1/2) = 15/4

Next, divide both sides by -3 to isolate (x + 1/2):

x + 1/2 = (15/4) / (-3)

x + 1/2 = -5/4

To isolate x, subtract 1/2 from both sides:

x = -5/4 - 1/2

Now, find a common denominator to subtract:

x = (-5/4) - (2/4)

x = (-5 - 2) / 4

x = -7/4

So, the solution to the equation (х + 1/2) / (-1/3) = 3 3/4 is:

x = -7/4
