Question

I am an integer. Double me and then add 7. Finally, subtract 10 and the result will be -27. What number am I?

Answer 1

the integer is -12

Explanation:

the integer is x

2x+7-10=-27

subtract 7 from both sides

2x-10=-34

add 10 to both sides

2x=-24

divide both sides by 2

x=-12

Answer 2

-12

Explanation:

-27+10=-17

-17-7=-24

-24/2=-12
