Plz answer

Answer 1

x=18

Explanation:

the result of 12 added to the difference of half a number and 3 is 45.

that looks something like this

`12+(1)/(2)x= 45`

which can be solved as such

`(1)/(1) x+(12-3)=45\\(1)/(2)x+9=45\\(1)/(2)x=45-9\\ (1)/(2)x=36\\(2)/(1)*(1)/(2)x=36*(2)/(1) \\  x=36*2\\x=72`
