Answer:

\boxed {x = \frac{13}{4}}

Step-by-step explanation:

Solve for the value of x:

(2x - 4) - 2 = 1 - 2(x - 3)

-Subtract 2 from 4:

(2x - 4) - 2 = 1 - 2(x - 3)

2x - 6 = 1 - 2(x - 3)

-Use <u>Distributive Property</u>:

2x - 6 = 1 - 2(x - 3)

2x - 6 = 1 - 2x - 6

-Add 2x to both sides:

2x - 6 + 2x = 1 - 2x + 2x - 6

4x - 6 = 7

-Add both sides by 6:

4x - 6 + 6 = 7 + 6

4x = 13

-Divide both sides by 4:

\frac{4x}{4} = \frac{13}{4}

\boxed {x = \frac{13}{4}}

Therefore, the value of x is \frac{13}{4}.
