What is the x in the problem x minus 12 over 2 equal 18?

Answer 1

You need to be careful in how you write such questions as it is important to know if you mean:

x - 12/2 = 18

or

(x-12)/2 = 18

If x - 12/2 = 18 then

x = 18 + 12/2

x = 18 + 6

x = 24

If (x-12)/2 = 18 then

x - 12 = 18 * 2

x - 12 = 36

x = 36 + 12

x = 48
