Answer:
Step-by-step explanation:
We have to write an equation to represent the relationship "a number decreased by negative 7 is the same thing as 48
Let the unknown number be x.
A number decreased by 7 = [tex]x-7[/tex]
Since this equals 48, algebraic equation would be
[tex]x-7=48[/tex]
Note: We can solve this by adding 7 to both sides to get x=55
