Answer: y= -10/21

Step-by-step explanation:

Hi, to answer this question we have to solve the equation given:

xy =10

So, we have to replace the value of x (variable)  in the expression by the number -21.

If x=-21,  

(-21) y =10

Solving for y:

y= 10/-21  

y= -10/21or -0.47 (decimal form)

Feel free to ask for more if needed or if you did not understand something.
