Answer 1

What must be subtracted from -3 to get -9?

Solution

Let the number to be subtracted from -3 to get -9 be = x

So the equation as per the given condition becomes

-3 -x=-9

-x=-9+3

-x=-6

x=6

Hence 6 must be subtracted from -3 to get -9

Answer 2

Answer:

Let us subtract 'x' from -3 to get -9. Let us now write this as an equation as:

-3 - x = -9

or, -3 - x + 3 = -9 + 3 (Adding 3 to both sides of the equation)

or, -x = -6

or, x = 6

Therefore, 6 must be subtracted from -3 to get -9.
