m∠ABD = m∠DBC


So, x + 15 = 4x - 12

3x = 27

x = 9

Since the problem asks for the value of x and this is an angle measurememt, you should probably add either the word "degrees" or the degree symbol to your answer. Normally, problems like this put the expressions inside parentheses and put the degree symbol outside the parentheses, making the variable a unitless number. But they didn't here. And some teachers can be picky about this.
