Answer:
Hello, we see that deepti has some boxes of crayons we dont know exactly how much so well name that a variable"x" Than we see that mani has 2 more boxes than deepti together they have 8 boxes.
Lets make the equation!
x+2=8
We have to solve for x all you have to do here is subtract 8 from 2 the answer is 6.
So 6+2=8
Hope i explained that right :)
