Question

Уравнение x+(x-1)=40

Answer 1

Ответ:

х=41/2 или х=20,5

Пошаговое объяснение:

x+(x-1)=40

х+х-1=40

2х-1=40

2х=40+1

2х=41

Answer 2

$x + (x - 1) = 40 \\ 2x - 1 = 40 \\ 2x = 41 \\ x = 20.5$

Answer 3

To solve the equation $x + (x - 1) = 40$, follow these steps:

Step 1: Combine like terms. $x + x - 1 = 40$

Step 2: Simplify the left side of the equation. $2x - 1 = 40$

Step 3: Isolate the variable term (2x) on one side by adding 1 to both sides. $2x = 41$

Step 4: Finally, divide both sides by 2 to solve for $x$. $x = \frac{41}{2}$

Therefore, the solution to the equation is $x = \frac{41}{2} = 20.5$.
