Question

Find the value of 6w-8 given that -5w - 6=4. Simplify your answer as much as possible.

Answer 1

From the given problem,

`-5w-6=4`

Solving for the value of w,

Add 6 to both sides of the equation

`\begin{gathered} -5w-6+6=4+6 \\ -5w=10 \end{gathered}`

Divide both sides by -5 :

`\begin{gathered} (-5w)/(-5)=(10)/(-5) \\ w=-2 \end{gathered}`

Now substitute the value of w to the asking expression.

`\begin{gathered} 6w-8=6(-2)-8 \\ =-12-8 \\ =-20 \end{gathered}`

The answer is -20
