Question

Find x when y is -81. Rule: y = -8x - 25

Answer 1

Answer: We have to find the value of x for the given value of y:

`y=-8x-25`

For the following we have:

`y=-81`
`\begin{gathered} -81=-8x-25 \\ \therefore\rightarrow \\ -8x=-81+25=-56\rightarrow x=(-56)/(-8)=7 \\ \therefore\rightarrow \\ x=7 \end{gathered}`
