Question

Which of the following for x makes the sentence true 10x-5=-45

Answer 1

Simplify the expression as follows;

`\begin{gathered} 10x-5=-45 \\ \text{Add 5 to both sides of the equation} \\ 10x-5+5=-45+5 \\ 10x=-40 \\ \text{Divide both sides by 10} \\ (10x)/(10)=(-40)/(10) \\ x=-4 \end{gathered}`

Option B is the correct answer.

The statement is true when x = -4
