Question

Solve each equation.

$-4x-28=0$

Step-by-Step Solution

Answer

The required solution is represented by $x=-7$.

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

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

Step 2. Determine the value of x .

Perform addition of 28 on both sides of the provided equation.

$$\begin{gathered} -4x-28+28=28 \\ -4x=28 \end{gathered}$$ 

Perform division of 4 on both sides of the equation.
