Simultaneous Equations <br> 2x+4y=22 <br> 2x+2y=15

Answer:

x = 4

y = $\frac{7}{2}$

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 = $-2y+11$

Then you have to subtitute $-2y+11$ for $x$ in $2x+2y=15$

which you then get y= $\frac{7}{2}$

After you have to subttitute y= $\frac{7}{2}$ for y in x = $-2y+11$

which you get as x=4

Finally you get the answer as:

x = 4

y = $\frac{7}{2}$
