Answer:

[tex]y=1,\:x=2[/tex]

Step-by-step explanation:

[tex]\begin{bmatrix}y=9x-17\\ y=-5x+11\end{bmatrix}[/tex]

[tex]\mathrm{Substitute\:}y=-5x+11[/tex]

[tex]\begin{bmatrix}-5x+11=9x-17\end{bmatrix}[/tex]

[tex]x=2[/tex]

[tex]\mathrm{For\:}y=-5x+11[/tex]

[tex]\mathrm{Substitute\:}x=2[/tex]

[tex]y=-5\cdot \:2+11[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]y=1[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]y=1,\:x=2[/tex]
