Question

Solve -2(3x - 1) = 20 for x.A) x = 5B) x = -3OC) x = 2D) x = -1

Answer 1

we have the equation

$-2\left(3x-1\right)=20$

Solve for x

step 1

Divide both sides by -2

$\begin{gathered} \frac{-2\left(3x-1\right)}{-2}=\frac{20}{-2} \\ simplify \\ 3x-1=-10 \end{gathered}$

step 2

Adds 1 on both sides

$\begin{gathered} 3x-1+1=-10+1 \\ 3x=-9 \end{gathered}$

step 3

Divide both sides by 3

$\begin{gathered} \frac{3x}{3}=\frac{-9}{3} \\ \\ x=-3 \end{gathered}$

The answer is option B
