Hello,

xy+xz=100==>x(y+z)=100
x/5*(3y+3z)+10=3/5*(x(y+z))+10=3/5*100+10=70

To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.

$\large\red{\sf{y=3x-1}}$

$\begin{gathered}\\ \sf\longmapsto 9=3(1)-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=3-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠2 \end{gathered}$

$\large\green{\sf{y=5x+4}}$

$\begin{gathered}\\ \sf\longmapsto 9=5(1)+4\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=5+4\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=9\end{gathered}$

$\large\blue{\sf{y=-2x-8}}$

$\begin{gathered}\\ \sf\longmapsto 9=-2(1)-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=-2-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠10\end{gathered}$

$\large\pink{\sf{y=6x-8}}$

$\begin{gathered}\\ \sf\longmapsto 9=6(1)-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=6-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠-2\end{gathered}$

Hence, Option B. y=5x+4 satisfies the system (1,9)
