Answer 1

Answer:

x=18

Step-by-step explanation:

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

that looks something like this

$12+\frac{1}{2}x= 45$

which can be solved as such

$\frac{1}{1} x+(12-3)=45\\\frac{1}{2}x+9=45\\\frac{1}{2}x=45-9\\ \frac{1}{2}x=36\\\frac{2}{1}*\frac{1}{2}x=36*\frac{2}{1} \\  x=36*2\\x=72$
