did you mean
7√2 x + 4√2 y = 82 ?
(that's "root" not "route")
how about multiplying the second equation by √2 ?
that would give you
14x + 8y = 82√2 or
7x + 4y = 41√2
I would then multiply the first equation by 4
and the last version of the second equation by 3,
then add them
take it from there.
Simultaneous equation and surds
5x-3y=41
(7route2)x+(4route2)y=82

i times them by 4 and 5 as you said and got
20x + 12y = 123
21x + 12y = 246�ã2
added together
21x = 123+246�ã2
is this right and if so can you help me get the next parts as i have tried but cant figure it out
thanks
