Question

Решите уравнение: 1)-4x =32; 2)-1,2x=-3,6 3)-2/7x=1/3

Answer 1

Ответ: 1) x = -9

2) x=7 целых 1/5

3) х = - 1 целая 1/6

Пошаговое объяснение: 1) -4x =32

x= 32:(-4)

x= - 9

2) -1/2x = -3,6

x = -3,6 : (-1/2)

x= 7целых 1/5

3) -2/7x = 1/3

x= 1/3 : (- 2/7)

x = - 1 целая 1/6

Answer 2

1. -4x = 32

To solve this equation, we want to isolate the variable x. We can do that by performing the same operation on both sides of the equation to maintain the balance.

First, let's divide both sides of the equation by -4 to isolate x:

(-4x) / -4 = 32 / -4

x = -8

So the solution to the equation -4x = 32 is x = -8.

2. -1.2x = -3.6

To solve this equation, we'll again isolate the variable x. In this case, we can divide both sides of the equation by -1.2:

(-1.2x) / -1.2 = -3.6 / -1.2

x = 3

Thus, the solution to the equation -1.2x = -3.6 is x = 3.

3. (-2/7)x = 1/3

To solve this equation, we'll isolate the variable x. First, we can multiply both sides of the equation by the reciprocal of (-2/7), which is (-7/2):

((-2/7)x) * (-7/2) = (1/3) * (-7/2)

The (-7/2) cancels out the (-2/7) on the left side, leaving us with:

x = (-7/2) * (1/3)

Simplifying the right side:

x = -7/6

Therefore, the solution to the equation (-2/7)x = 1/3 is x = -7/6.
