Question

A) 4(x + 1) + 11 = 31;​

Answer 1

Ответ:

х = 4.

Пошаговое объяснение:

4(х + 1) + 11 = 31

4х + 4 + 11 = 31

4х = 31 - 11 - 4

4х = 16

х = 16 : 4

х = 4.

Answer 2

Ответ:

х=4

Пошаговое объяснение:

4х+4+11 =31

4х= 31-11-4

4х =16

х=4

Answer 3

To solve the equation 4(x + 1) + 11 = 31, follow these steps:

1. First, distribute the 4 on the left side of the equation to eliminate the parentheses:

4(x + 1) + 11 = 31 4x + 4 + 11 = 31

2. Combine like terms by adding 4 and 11 on the left side:

4x + 15 = 31

3. Now, subtract 15 from both sides of the equation to isolate the variable x:

4x + 15 - 15 = 31 - 15 4x = 16

4. Finally, divide both sides by 4 to solve for x:

4x/4 = 16/4 x = 4

So, the solution to the equation is x = 4.
