Answer:


x=13,\:y=0

Explanation:

Isolate x for 2x-3y=26:
x=(26+3y)/(2)


\mathrm{Substitute\:}x=(26+3y)/(2)


\begin{bmatrix}3\cdot (26+3y)/(2)-4.6y=39\end{bmatrix}


Simplify


\begin{bmatrix}39-0.1y=39\end{bmatrix}

Isolate y for 39-0.1y=39: y=0


\mathrm{For\:}x=(26+3y)/(2)


\mathrm{Substitute\:}y=0


x=(26+3\cdot \:0)/(2)


(26+3*0)/(2)=13


x=13


\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}


x=13,\:y=0
