Question

if $-18 = 6 - 12x$, what is the value of $1 - 2x$?
choose 1 answer:
a $-4$
b $-3$
c $2$
d $3$

Explanation:

Step1: Isolate the term with $x$

Subtract 6 from both sides:
$-18 - 6 = 6 - 12x - 6$
$-24 = -12x$

Step2: Solve for $x$

Divide both sides by $-12$:
$\frac{-24}{-12} = \frac{-12x}{-12}$
$x = 2$

Step3: Substitute $x$ into $1-2x$

Calculate the expression:
$1 - 2(2) = 1 - 4$

Answer:

A. -4
