Answer:

x = 4

y = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Ummmm

I'm not sure if this is corrrect but this is what I got

So first you solve 2x+4y=22 to find x

and you get x = [tex]-2y+11[/tex]

Then you have to subtitute [tex]-2y+11[/tex] for [tex]x[/tex] in [tex]2x+2y=15[/tex]

which you then get y= [tex]\frac{7}{2}[/tex]

After you have to subttitute y= [tex]\frac{7}{2}[/tex]  for y in x = [tex]-2y+11[/tex]

which you get as x=4

Finally you get the answer as:

x = 4

y = [tex]\frac{7}{2}[/tex]
