Question

X/8-x/12=-1/35x/14+3x/4=4 3/7помогите пожалуйста!!​

Answer 1

Ответ:

Пошаговое объяснение:

х/8 - х/12 = -1/3  | *24

3х - 2х = -8

х = -8

5х/14 + 3х/4 = 4. 3/7 | *28

2*5х + 7*3х = 31/7 * 28

10х + 21х = 31/1 * 4

31х = 124/1

31x = 124

х = 124 : 31

х = 4

Answer 3

Solving the Equation X/8 - X/12 = -1/35:

To solve the equation X/8 - X/12 = -1/35, we can follow these steps:

1. Find a common denominator for the fractions. 2. Combine the fractions on the left-hand side of the equation. 3. Solve for X.

Let's start by finding a common denominator for the fractions on the left-hand side.

The common denominator for 8 and 12 is 24. Therefore, we can rewrite the equation as:

X/24 - 2X/24 = -1/35

Now, we can combine the fractions:

-X/24 = -1/35

To solve for X, we can multiply both sides of the equation by -24 to get rid of the fraction:

X = 24/35

So, the solution to the equation X/8 - X/12 = -1/35 is X = 24/35.

Solving the Equation x/14 + 3x/4 = 4 + 3/7:

To solve the equation x/14 + 3x/4 = 4 + 3/7, we can follow these steps:

1. Find a common denominator for the fractions. 2. Combine the fractions on the left-hand side of the equation. 3. Solve for x.

Let's start by finding a common denominator for the fractions on the left-hand side.

The common denominator for 14 and 4 is 28. Therefore, we can rewrite the equation as:

2x/28 + 21x/28 = 4 + 3/7

Now, we can combine the fractions:

23x/28 = 31/7

To solve for x, we can multiply both sides of the equation by 28 to get rid of the fraction:

23x = 124

Finally, we can solve for x:

x = 124/23

So, the solution to the equation x/14 + 3x/4 = 4 + 3/7 is x = 124/23.
