Answer 2

Given :   ( - 7) × ( )  = 21

5  × ( )  = 30  

To Find : Fill in the blank so  Equation becomes correct

Solution:

( - 7) × ( )  = 21

=> ( - 7) × (x)  = 21

=> x = 21/( - 7)

=> x = - 3

 ( - 7) × ( -3 )  = 21

5  × ( )  = 30  

=>  5  × ( y)  = 30  

=> y = 30/5

=> y = 6

5  × (6 )  = 30
