Question

7)Solve the equation for x.3(2x– 12x) = 30

Answer 1

x=-1

Explanation

$3(2x-12x)=30$

Step 1

apply distributive property

$\begin{gathered} 3(2x-12x)=30 \\ 6x-36x=30 \\ \\ \end{gathered}$

Step 2

add similar terms

$\begin{gathered} 6x-36x=30 \\ -30x=30 \end{gathered}$

Step 3

divide each side by -30

$\begin{gathered} -30x=30 \\ \frac{-30x}{-30}=\frac{30}{-30} \\ x=-1 \end{gathered}$

so, the answer is x=-1
