Question

A number decreased by 16 is -3.

Answer 1

Answer:

Step-by-step explanation:

First let’s imagine our answer is x

”decreased means subtraction”

so we will subtract 16 from x and it should equal -3...

x-16=-3

now we need 16 to crossover to the other side of the equal sign...

(remember 16 is now positive)

x=-3+16

and now you can solve...

x=13
