You can add the whole numbers as is.
2 + 16 = 18
Add the fractions with the same denominator.
Find the common denominator between 5 and 9.
The common denominator should be 45.
Write both fractions with a denominator of 45.
3/5 → 27/45
4/9 → 20/45
Add the new fractions as is:
27/45 + 20/45 = 47/45
Write 47/45 as a mixed fraction.
47/45 → 1 2/45
Add both the whole number and the mixed fraction.
18 + 1 2/45 = 19 2/45
Solution: C) 19 2/45g

The two probabilities <em>are not equal</em>.
X=5 and y =2.
Here's how you do it.
Multiply the first equation by -3, and the second one by 1.
add the equations to eliminate x.
then solve for y by dividing both sides by -5, which gives us 2.
to solve for x subsitute 2 in for y.
