Answer 2

To find the value of x in each equation, we can solve them one by one:

1. 5 - x = x - 1

To solve this equation, we need to isolate x on one side of the equation:

Add x to both sides: 5 - x + x = x - 1 + x

Simplify: 5 = 2x - 1

Add 1 to both sides: 5 + 1 = 2x - 1 + 1

Simplify: 6 = 2x

Divide both sides by 2: x = 6 / 2 x = 3

So, x = 3 for the first equation.

2. x - 6 = 4x + 3

To solve this equation, we need to isolate x on one side of the equation:

Subtract x from both sides: x - 6 - x = 4x + 3 - x

Simplify: -6 = 3x + 3

Subtract 3 from both sides: -6 - 3 = 3x + 3 - 3

Simplify: -9 = 3x

Divide both sides by 3: x = -9 / 3 x = -3

So, x = -3 for the second equation.

3. 2x + 4 = x + 3

To solve this equation, we need to isolate x on one side of the equation:

Subtract x from both sides: 2x + 4 - x = x + 3 - x

Simplify: x + 4 = 3

Subtract 4 from both sides: x + 4 - 4 = 3 - 4

Simplify: x = -1

So, x = -1 for the third equation.

4. 2x = x + 1

To solve this equation, we need to isolate x on one side of the equation:

Subtract x from both sides: 2x - x = x + 1 - x

Simplify: x = 1

So, x = 1 for the fourth equation.
