What is Q if 7 is added to it and 10 removed from it thw answer is 10

1 answer

Let's use algebra to solve this problem.

Let Q be the original number.
Given that when 7 is added to Q and 10 is removed from it, the result is 10. We can write this as an equation:

(Q + 7) - 10 = 10

Simplify the equation:
Q + 7 - 10 = 10
Q - 3 = 10

Add 3 to both sides of the equation:
Q - 3 + 3 = 10 + 3
Q = 13

Therefore, the original number Q is 13.
