The system of equation are:


\begin{gathered} 3x+2y=17 \\ 4x+6y=26 \end{gathered}

to solve this problem we can solve the second equation for x so:


\begin{gathered} 4x=26-6y \\ x=6.5-1.5y \end{gathered}

Now we can replace x in the firt equation so:


3(6.5-1.5y)+2y=17

and we can solve for y so:


\begin{gathered} 19.5-4.5y+2y=17 \\ 19.5-17=2.5y \\ 2.5=2.5y \\ (2.5)/(2.5)=1=y \end{gathered}

Now we replace the value of y in the secon equation so:


\begin{gathered} x=6.5-1.5(1) \\ x=5 \end{gathered}

So the solution as a ordered pair is:


(x,y)\to(5,1)
