Answer:

x= [tex]4\frac{2}{3}[/tex]

y= [tex]17\frac{1}{3}[/tex]

Step-by-step explanation:

[tex]5x-y=6\\-2x+y=8\\[/tex]

Simplify, find the x-value first:

[tex]3x=14\\x=4\frac{2}{3}[/tex]

Substitute x-value into any equation (i did the second equation) and simplify:

[tex]-2(4\frac{2}{3})+y=8\\ -9\frac{1}{3} +y=8\\[/tex]

[tex]y=17\frac{1}{3}[/tex]
