Question

5 (×+3)-2 (5+×)=15 (×+4)​

Answer 1

$5(x + 3) - 2(5 + x) = 15(x + 4) \\ 5x + 15 - 10 - 2x = 15x + 60 \\ 5x - 2x - 15x = 60 - 15 + 10 \\ - 12x = 55 \\ x = - \frac{55}{12} = - 4\frac{7}{12} .$

Ответ : -4 7/12.

Answer 2

5 ( х + 3 ) - 2 ( 5 + х ) = 15 ( х + 4 )

5х + 15 - 10 - 2х = 15х + 60

5х - 2х - 15х = 60 - 15 + 10

-12х = 55

х = -55/12 = -4 7/12.

Ответ : х = - 4 7/12.

Answer 3

Let's solve the equation step by step:

1. Distribute the terms on both sides of the equation: 5x + 15 - 2(5 + x) = 15x + 60

2. Remove the parentheses: 5x + 15 - 10 - 2x = 15x + 60

3. Combine like terms: (5x - 2x) + (15 - 10) = 15x + 60

4. Simplify further: 3x + 5 = 15x + 60

5. Now, let's get all the x terms on one side of the equation and the constants on the other side. We'll do this by subtracting 3x from both sides: 3x + 5 - 3x = 15x + 60 - 3x

6. Simplify the equation again: 5 = 12x + 60

7. Now, we'll isolate the variable x by moving the constant term to the other side. We'll do this by subtracting 60 from both sides: 5 - 60 = 12x + 60 - 60

8. Simplify further: -55 = 12x

9. Finally, solve for x by dividing both sides by 12: x = -55 / 12

The solution to the equation is: x ≈ -4.58 (rounded to two decimal places)
