Question

-8x - 9 = -21 I need help with this equation please

Answer 1

To solve the equation for x, first, we add 9 from both sides:

`\begin{gathered} -8x-9=-21 \\ -8x-9+9=-21+9 \\ -8x=-12 \end{gathered}`

Now, we divide by -8 from both sides of the equation:

`\begin{gathered} (-8x)/(-8)=(-12)/(-8) \\ x=1.5 \end{gathered}`

Therefore, the solution of the given equation is 1.5.
