Answer 2

Given:

1. $16, (-19)$
2. $28, (-41)$

To find:

1. What must be added to $16$ to make it $-19$
2. The difference when $28$ is subtracted from $-41$

Step-by-step explanation:

• Here we need to apply some rules for addition and subtraction.

$-,- = +\\\\-,+ = -\\\\+,-= -\\\\+,+ = +$

Solution:

1. We need to add something to $16$ to make it$-19$

We will assume that number to be $=x$

now,

$16 +x = -19\\\\x = -19 -16\\\\x= -35$

Hence the solution is $-35$

2. We need to find the difference when $28$ is subtracted from $-41$

now,

$-41 -28\\\\=-69$

Hence, the difference is $-69$
