Answer 1

have you tried anything at all? ... or you don't know how to start it ? :)

Answer 2

didn't know how too start and just dk how to do it

Answer 3

ok, so you have:

2x + 3y = 11
5x + 3y = 5

let's start from the first equation:
2x + 3y = 11
we'll solve it for X
2x=11-3y
now let's divide both sides by 2 and we'll have X alone in the left side:
\[\Large \frac{2x}{2}=\frac{11}{2}-\frac{3y}{2}\]
\[\Large x=\frac{11}{2}-\frac{3y}{2}\]

now take the second equation... and substitute X

\[\Large 5x+3y=5\]
\[\Large 5\left(\frac{11}{2}-\frac{3y}{2}\right)+3y=5\]
now multiply\simplify anything that you havet o.. and find y, then tell me what did you get. I'd be delighted to check it :) ...if you get stuck somewhere just let me know.
