Question

Find the root of each equation.

$0=2x+8$

Short answer

The required root is represented by $x=-4$.

Step-by-step solution

Step 1. Determine the method which can be used to determine the required root.

The equation that represents the value of x will represent the required root.

Step 2. Determine the value of x. 

Perform subtraction of 8 from both sides of the provided equation.

$$\begin{gathered} -8=2x+8-8 \\ -8=2x \end{gathered}$$

Perform division of 2 from both sides of the equation.

$\begin{array}{c}\frac{-8}{2}=\frac{2x}{2}\\ -4=x\\ x=-4\end{array}$

Step 3. Write the conclusion.

The obtained equation$x=-4$ is the required root.
