Hi there!

Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :

(x -
(3)/(4)) +
(5)/(4) = -7

subtract
(5)/(4) on each side of the equation


x -
(3)/(4) = -8.25

add
(3)/(4) on each side of the equation

x = -7.5


-7.5 - 3/4 = -8.25

-8.25 + 5/4 = -7


So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.


There you go! I really hope this helped, if there's anything just let me know! :)
