8x + 3y = 45 * -2 Negative
2x + 3y = 27 * 8 Positive

-16x - 6y = 90
16x + 24y = 216

24y is equal to 216
y is equal to 216/or 24
y is equal to 9

Which means:
8 + 3y = 216
y = 216/24
y = 9


8x + 3y = 45
8x + 3 (Which is 9) = 45

So the Answer is:
8x=45 - 27
8x= 18
X=18/8
X= 2.25



Hope this helps you
(Good Luck)
