See entire simplification process below:

Explanation:

First, take each mixed fraction and convert it into an improper fraction:

-((2/2 xx 7) + 1/2) + ((3/3 xx 5) + 1/3)

-(14/2 + 1/2) + (15/3 + 1/3)

-15/2 + 16/3

Next, we need to get each fraction over a common denominator (in this case 6) so we can add the fractions. We do this by multiplying each fraction by the appropriate form of 1:

(-15/2 xx 3/3) + (16/3 xx 2/2)

-45/6 + 32/6

Now, we can add the fractions:

(-45 + 32)/6

-13/6

Or

-2 1/6
