If $2(3x - 5) - 4x = 14$ , what is the value of $x$ ?

$2$

$9.5$

$12$

$24$

Show answer and explanation

Answer: C

Distribute: $6x - 10 - 4x = 14$ . Combine like terms: $2x - 10 = 14$ . Add 10: $2x = 24$ . Divide by 2: $x = 12$ .

Choice B comes from not distributing the 2 to the $-5$ , which gives $2x - 5 = 14$ .
