Question

Write the sentence as an algebraic equation and find its solution.

Twice a number equals $-14$.

Answer 1

Step 1: Write the equation

Let, the number be $x$.

So, the equation is $2x=-14$

Step 2: Solve the equation

$$\begin{gathered} 2x=-14 \\ \Rightarrow x=\frac{-14}{2} \\ \Rightarrow x=-7 \end{gathered}$$

Hence, the solution of the equation is $-7$.
