4 times a number decreased by 2 is 5

Answer 1

4N-2 = 5

4N =5+2 = 7

N = 7/4 = 1.75

the Number is 1.75 = 1 3/4 = 7/4

4(7/4) -2 = 7-2 = 5

UNLESS you really meant

4(N-2) = 5

N-2 = 5/4

N = 5/4 +2 = 13/4 = 3.25 = 3 1/4

but odds are you want the 1st answer, 7/4, if you follow PEMDAS order of operations, multiplication comes before subtraction, so multiply 4N first, then subtract 2, Not N-2 then multiplying by 4
