Question

(x + 1)+ 5 = 3; (x + 5) - 2 = 7.​

Answer 1

1)

(x + 1) + 5 = 3

x + 1 + 5 = 3

x + 6 = 3

x = 3 - 6

Ответ: x = -3

2)

(x + 5) - 2 = 7

x + 5 - 2 = 7

x + 3 = 7

x = 7 - 3

Ответ: x = 4

Answer 2

Let's solve the given equations step by step:

Equation 1: (x + 1) + 5 = 3

First, simplify the equation by combining like terms: x + 1 + 5 = 3 x + 6 = 3

Next, isolate the variable x by subtracting 6 from both sides: x + 6 - 6 = 3 - 6 x = -3

Therefore, the solution for Equation 1 is x = -3.

Equation 2: (x + 5) - 2 = 7

Again, simplify the equation by combining like terms: x + 5 - 2 = 7 x + 3 = 7

To isolate the variable x, subtract 3 from both sides: x + 3 - 3 = 7 - 3 x = 4

So, the solution for Equation 2 is x = 4.

In summary, the solutions for the given equations are: Equation 1: x = -3 Equation 2: x = 4
