Question

1) 3(1-8) + 5 (x+2) =1-48​

Answer 1

Ответ:

x = -7.2

Пошаговое объяснение:

3(1-8)+5(x+2) = 1-48

3-24+5x+10 = 1-48

5x = -47-3+24-10

5x = -36

x = -7.2

Answer 2

Ответ:

-7,2

Пошаговое объяснение:

3 × (1 - 8) + 5 × (x + 2) = 1 - 48​

3 × (- 7) + 5х + 10 = - 47

- 21 + 5х + 10 = - 47

5х = - 47 + 21 - 10

5х = - 36

х = - 36 ÷ 5

х = $-7\frac{1}{5}$

х = $-7\frac{2}{10}$

х = - 7,2

Проверка:

3 × (1 - 8) + 5 × (-7,2 + 2) = 1 - 48​

3 × (- 7) + 5 × (-5,2) = - 47

- 21 - 26 = - 47

- 47 = - 47

Верно!

Answer 3

To solve the equation 3(1-8) + 5(x+2) = 1-48, follow these steps:

Step 1: Simplify both sides of the equation. On the left side, simplify the expressions within the parentheses: 3 * (-7) + 5(x + 2) = 1 - 48 -21 + 5(x + 2) = -47

Step 2: Distribute the 5 on the left side. -21 + 5x + 10 = -47

Step 3: Combine like terms on the left side. -11 + 5x = -47

Step 4: Move -11 to the right side by adding 11 to both sides. 5x = -47 + 11 5x = -36

Step 5: Solve for x by dividing both sides by 5. x = -36 / 5 x = -7.2

So, the solution to the equation is x = -7.2.
