Question

Three-fourths was subtracted from a number, and then 5/4 was added to the result. The sum was -7.

Answer 1

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! :)
