The value of x in the equation is -5
Here, we want to find the value of x in the given equation
What this simply means is to find the value of x that makes the equation true
We proceed as follows;
We start by opening the bracket and isolating the term that has the x-term
Thus, we have;
[tex]\begin{gathered} 8x\text{ + 40 = 0} \\ \\ 8x\text{ = -40} \\ \\ x\text{ = }\frac{-40}{8} \\ \\ x\text{ = -5} \end{gathered}[/tex]
