Short answer (Assuming you are trying to find the value of n):
Equation solution: -2.5
Value of n: -3.25
I assume you wanna find the value of n
First step is to do the first equation
remember that that / sign is division
-5 divided by 2 = -2.5
Now start the equation with n
3 divided by 4 = 0.75
so n must be a negative because that is the only way the number will go into the negatives when your adding
Since subtracting a positive is the same as adding a negative, we can just find the number that when subtracted from 0.75 gives us -2.5 and flip the sign.
0.75 - 3.25 = -2.5
Your answer is -3.25
