1. (154-x)+39=125 2. 77-(x+26)=13

Answer 1

Ответ:

Пошаговое объяснение:

1. (154-x)+39=125

х=154+39-125

х=68

2. 77-(x+26)=13

77-х-26=13

х=77-26-13

х=38

Answer 2

1) (154 - х) + 39 = 125
154 - х + 39 = 125
193 - х = 125
-х = 125 - 193
-х = -68
х = 68

2) 77 - (х + 26) = 13
77 - х - 26 = 13
51 - х = 13
-х = 13 - 51
-х = -38
х = 38

Answer 3

Let's solve each equation step by step:

1. (154 - x) + 39 = 125

First, let's simplify the equation by combining like terms:

154 - x + 39 = 125

Next, let's isolate the variable x by moving the constants to the other side of the equation:

• x + 193 = 125

Now, let's solve for x by subtracting 193 from both sides:

• x = 125 - 193

Simplifying further:

• x = -68

To solve for x, we can multiply both sides by -1 to change the sign:

x = 68

Therefore, the solution to the equation is x = 68.

2. 77 - (x + 26) = 13

Let's simplify the equation:

77 - x - 26 = 13

Combine like terms:

51 - x = 13

Now, let's isolate the variable x by moving the constant to the other side:

• x = 13 - 51

Simplifying further:

• x = -38

Multiply both sides by -1 to change the sign:

x = 38

Therefore, the solution to the equation is x = 38.
