Question

solve the following equation: 3-n/2=3/4

Answer 1

please show me how to do this

Answer 2

subtract 3 from each side:
-n/2 = 3/4-3
= -2 1/4
mult by 2:
-n = -4 1/2
mult by -1
n = 4 1/2 or 9/2

Answer 3

... or if it is (3-n) / 2 = 3/4, then
mult by 2:
3-n = 3/2
subtract 3:
-n = -3/2
mult by -1:
n = 3/2
