Answer 1

5 - 2( х - 1 ) = 4 - х

5 - 2х + 2 = 4 - х

7 - 2х = 4 -х

- 2х + х = 4 - 3

- х = - 3

х = 3

Answer 3

To solve the equation 5 - 2(x - 1) = 4 - x, we can follow these steps:

Step 1: Distribute the -2 to the terms inside the parentheses: 5 - 2x + 2 = 4 - x

Step 2: Combine like terms on both sides of the equation: -2x + 7 = 4 - x

Step 3: Move all the terms with x to one side of the equation by adding x to both sides: -2x + x + 7 = 4

Simplifying the left side: -x + 7 = 4

Step 4: Move the constant term to the other side of the equation by subtracting 7 from both sides: -x + 7 - 7 = 4 - 7

Simplifying: -x = -3

Step 5: Solve for x by multiplying both sides of the equation by -1: -1 * -x = -1 * -3

Simplifying: x = 3

Therefore, the solution to the equation 5 - 2(x - 1) = 4 - x is x = 3.
