Answer:

[tex]x=3[/tex]

[tex]y=1[/tex]

Step-by-step explanation:

We can subtract the first equation from the second to find the value of [tex]y[/tex], although we can also do this vice versa.

[tex]x-x=2y+1-y-2[/tex]

[tex]y-1=0[/tex]

[tex]y=1[/tex]

Now, we can use substitution to solve for [tex]x[/tex]:

[tex]x = y+2[/tex] (pick any equation for substitution)

[tex]x=1+2[/tex]

[tex]x=3[/tex]

Hope this helps :)
