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

Rasek [7]

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 - $\frac{3}{4}$ ) + $\frac{5}{4}$ = -7

subtract $\frac{5}{4}$ on each side of the equation

x - $\frac{3}{4}$ = -8.25

add $\frac{3}{4}$ on each side of the equation

x = -7.5

-7.5 - 3/4 = -8.25

-8.25 + 5/4 = <u>-7</u>

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! :)
