Question

Пожалуйста помогите, правильно решить!!! Решите уравнения, воспользовавшись свойствами уравнений: Эти уравнения / с дробью обыкновенной!!! 1) -5х/2 = 10 2) -7х/3=14 3) 2х/3= -4 4) 3х/2= -6 / это обозначает дробь Помогите прошу!!! Я думаю что есть на свете люди с доброй душой которые могут помочь!!! Пожалуйста объясните как это всё делать, пожалуйста!!! Я даже даю баллы хорошие 40 !!!

Answer 1

1)-5х/2=10
    -5х=10*2
    -5х=20
     х=20/(-5)
     х=-4
    Ответ: -4
2)-7х/3=14
-7х=14*3
-7х=42
х=42:(-7)
х=-6
Ответ: -6.
3)2х/3=-4
2х=-4*3
2х=-12
х=-12:2
х=-6
Ответ: -6.
4)3х/2=-6
3х=-6*2
3х=-12
х=-12:3
х=-4
Ответ: -4.

Answer 2

Solving Equations with Fractions

To solve equations with fractions, we can use the properties of equations to isolate the variable on one side of the equation. Let's solve the given equations step by step:

Equation 1: -5x/2 = 10

To solve this equation, we can multiply both sides of the equation by the reciprocal of the fraction (-2/5) to eliminate the fraction:

-5x/2 * (-2/5) = 10 * (-2/5)

Simplifying the equation gives us:

x = -20/5

Simplifying the fraction gives us:

x = -4

Equation 2: -7x/3 = 14

To solve this equation, we can follow the same steps as before:

-7x/3 * (-3/7) = 14 * (-3/7)

Simplifying the equation gives us:

x = -42/7

Simplifying the fraction gives us:

x = -6

Equation 3: 2x/3 = -4

To solve this equation, we can follow the same steps as before:

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

Simplifying the equation gives us:

x = -12/2

Simplifying the fraction gives us:

x = -6

Equation 4: 3x/2 = -6

To solve this equation, we can follow the same steps as before:

3x/2 * (2/3) = -6 * (2/3)

Simplifying the equation gives us:

x = -12/3

Simplifying the fraction gives us:

x = -4

Therefore, the solutions to the given equations are:

1) x = -4 2) x = -6 3) x = -6 4) x = -4
