Question

The sum of a number and -16 is 25. Find the number.

Answer 1

Answer:

$\huge{ \fbox{ \sf{41}}}$

Step-by-step explanation:

$\star{ \sf{ \: Let \: the \: missing \: number \: be \: x}}$

Create an equation

$\sf{x + ( - 16) = 25}$

$\mapsto{ \sf{x - 16 = 25}}$

Move 16 to right hand side and change it's sign

$\mapsto{ \sf{x = 25 + 16}}$

Add the numbers : 25 and 16

$\mapsto{ \sf{x = 41}}$

The number is 41
