To solve this arithmetic expression, we need to find a common denominator for the fractions -12/7 and 3/14. The common denominator is 14.
Next, we can rewrite -12/7 as (-12/7) * (2/2) = -24/14.
Now, the expression becomes (-24/14) + 3/14.
To add the fractions, we keep the denominator the same and add the numerators: (-24 + 3) / 14 = -21/14.
Therefore, -12/7 + 3/14 equals -21/14.
