Answer:

[tex]x=0.75, y=-0.25[/tex]

Step-by-step explanation:

We can add the two equations to eliminate [tex]y[/tex] and solve for [tex]x[/tex].

[tex]x+y+x-y=0.5+1[/tex]

[tex]2x=1.5[/tex]

[tex]x=0.75[/tex]

Now, we can find for [tex]y[/tex] by using substitution:

[tex]x+y=0.5[/tex] (given)

[tex]0.75+y=0.5[/tex]

[tex]y=-0.25[/tex]

Hope this helps :)
