A number increased by-56 is -82 find the number

Answer 1

We'll use x for the mystery number.

Our question looks like

x + (-56) = -82

You can drop the parentheses and it just becomes a subtraction

x - 56 = -82

To get x by itself, add 56 to both sides and solve

x - 56 + 56 = -82+56

x = -26

To check your work place -26 back into the original place of x:

(-26) + (-56) = -82
