Answer:
[tex]n+7=48[/tex]
Step-by-step explanation:
Let n represent the number.
We are supposed to write an equation for the given word phrase.
A number decreased by negative 7 mean negative 7 is subtracted from the number: [tex]n-(-7)[/tex].
A number decreased by negative 7 is the same thing as 48. We will equate 48 to [tex]n-(-7)[/tex] find our required equation as:
[tex]n-(-7)=48[/tex]
Simplify:
[tex]n+7=48[/tex]
Therefore, our required equation is [tex]n+7=48[/tex].
