x=16

Step-by-step explanation

given the function


6x-y=98

Step 1

as we need x is terms of y, let's solve for x


6x-y=98

a) add y in both sides


\begin{gathered} 6x-y+y=98+y \\ 6x=98+y \end{gathered}

b) divide both sides by 6


\begin{gathered} 6x=98+y \\ (6x)/(6)=(98+y)/(6) \\ x=(98)/(6)+(y)/(6)\Rightarrow equation \\ \end{gathered}

Step 2

now, evaluate for y=-2


\begin{gathered} x=(98)/(6)+(y)/(6)\operatorname{\Rightarrow}equat\imaginaryI on \\ replace \\ x=(98)/(6)-(2)/(6) \\ x=(96)/(6)=16 \\ x=16 \end{gathered}

therefore, the answer is

x=16

I hope this helps you
