Step-by-Step Solution

First let's remember the rule:

(x)=+ -(-x)=+

Now let's rewrite the exercise like so:

?+3+10=40 ?+3+10=-40

?+13=40 ?+13=-40

Then we can add -13 to both sides to cancel out the left side:

?+1313=4013 ?+13-13=-40-13

Finally, we get:

?+0=53 ?+0=-53

?=53 ?=-53

Answer

53 -53
