Question

Simultaneous Equations
2x+4y=22
2x+2y=15

Answer 1

x = 4

y =
`(7)/(2)`

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=
`(7)/(2)`

After you have to subttitute y=
`(7)/(2)` for y in x =
`-2y+11`

which you get as x=4

Finally you get the answer as:

x = 4

y =
`(7)/(2)`
