Question

5) (x +1| + 5 = 3;6) (x + 5) - 2 = 7.​

Answer 1

$(x + 1) + 5 = 3 \\ x + 1 + 5 = 3 \\ x + 6 = 3 \\ x = 3 - 6 \\ x = - 3$

$(x + 5) - 2 = 7 \\ x + 5 - 2 = 7 \\ x + 3 = 7 \\ x = 7 - 3 \\ x = 4$

Answer 2

Ответ:

5. х = -3

6. х = 4

Пошаговое объяснение:

5) (x +1) + 5 = 3

х + 1 + 5 = 3

х = 3 - 1 - 5

х = 3 - 6

х = -3

Проверим: (-3 + 1) + 5 = -2 + 5 = 3

6) (x + 5) - 2 = 7

х + 5 - 2 = 7

х = 7 - 5 + 2

х = 4

Проверим: (4 + 5) - 2 = 9 - 2 = 7

Answer 3

To solve these equations, let's solve them one by one:

1. (x + 1) + 5 = 3

First, let's simplify the equation by removing the parentheses:

x + 1 + 5 = 3

Combine like terms:

x + 6 = 3

Next, let's isolate x by subtracting 6 from both sides:

x + 6 - 6 = 3 - 6

x = -3

Therefore, the solution to the first equation is x = -3.

2. (x + 5) - 2 = 7

Again, let's simplify the equation by removing the parentheses:

x + 5 - 2 = 7

Combine like terms:

x + 3 = 7

Next, let's isolate x by subtracting 3 from both sides:

x + 3 - 3 = 7 - 3

x = 4

Therefore, the solution to the second equation is x = 4.

In summary:

1. x = -3
2. x = 4
