We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
we have the expression

Evaluate for x=-4/5 and y=1/3
substitute the values of x and y in the given expression

the answer is 32/15
