Explanation:

what's the problem ?

you need to just calculate the result ?

if so, then just enter the values at the corresponding locations of the variable names and then ... calculate.

you made some typos here, so it is not clear what n is supposed to be.

is it

n = 1/4

or

n = -1/4

?

and are there any other typos here that are not obvious but change the problem ?

I can see here the basic expression

4(n + 3) - 5r

r = 1/5

n is the "?" as described above.

so I will do both cases with the expression i could see here.

n = 1/4

4(1/4 + 3) - 5×1/5 = 4×1/4 + 4×3 - 5×1/5 = 1 + 12 - 1 = 12

n = -1/4

4(-1/4 + 3) - 5×1/5 = -4×1/4 + 4×3 - 5×1/5 = -1 + 12 - 1 = 10

please pick the one that fits to the original problem description.
