Question

А) -54 - х = 26; б) х + (-57) = - 83.

Answer 1

Ответ:

Пошаговое объяснение:

а) -54 - х = 26

  -х = 26 + 54

  -х = 80

  х= -80

б) х + (-57) = -83

   х - 57 = -83

  х = -83 + 57

  х = - 26

Answer 2

а) -х= 26 + 54 = 80

х = -80

ответ: -80

б) х = -83 + 57 = -26

х = -26

ответ: -26

Answer 3

To solve the equations, we need to find the value of the variable "x" that satisfies each equation.

А) -54 - x = 26

To isolate the variable "x," we can follow these steps:

Step 1: Add 54 to both sides of the equation to move the constant term to the right side: -54 + 54 - x = 26 + 54

Simplified:

• x = 80

Step 2: Now, we want to get the variable "x" by itself, so we multiply both sides by -1 to change the sign: -1 * (-x) = -1 * 80

Simplified: x = -80

So the solution to equation А) is x = -80.

Б) x + (-57) = -83

To isolate the variable "x," we can follow these steps:

Step 1: Add 57 to both sides of the equation to move the constant term to the right side: x + (-57) + 57 = -83 + 57

Simplified: x = -26

So the solution to equation Б) is x = -26.

Therefore, the solutions are: А) x = -80 Б) x = -26
