Answer 1

Since no one else will lol

You are given:
\(\large 5x+2y=7 \)
\(\large -2x+6y=9 \)

To find the value of y, you'll need to get rid of x, so multiply the top by 2, and the bottom by 5:

\(\large 2(5x+2y=7) \)
\(\large 5(-2x+6y=9) \)

You end up with:
\(\large 10x +4y=14\)
\(\large -10x+30y=45 \)

Now you can add the x's, which will be zero and get:
\[\large 34y=59 \]
Just divide and you get:
\[\large y=\frac{59}{34} \]

Just plug that into a calculator.
