Answers

\begin{cases} y= (3 )/(4)x-7 \n 4x- 6y=50 \end{cases}\n \n\begin{cases} y= (3 )/(4)x-7 \n 4x- 6((3 )/(4)x-7)=50 \end{cases}\n \n\begin{cases} y= (3 )/(4)x-7 \n 4x- (9 )/(2)x+42=50 \end{cases}\n \n \begin{cases} y= (3 )/(4)x-7 \n 4x- 4(1 )/(2)x =50 -42\end{cases}

\begin{cases} y= (3 )/(4)x-7 \n - (1 )/(2)x =8 \ \ /*(-2)\end{cases}\n \n \begin{cases} y= (3 )/(4)*(-16)-7 \n x =-16\end{cases}\n \n \begin{cases} y= -12-7 \n x =-16\end{cases} \n \n\begin{cases} y= -19 \n x =-16\end{cases}


Y=3/4x-7
4x-6y=50

4x-6y=50
4x-6(3/4x-7)=50
4x-18/4x+42=50

x=-16

y=3/4(-16)-7
y=-12-7
y=-19
