SOLUTION: My question is a quadratic equation: 8x+27=5x. I tried to solve by subtracting 8x by 5x. the 3x +27=0. I subtracted 27 and got 3x= -27. After that I got 3x= -27. My answer was x= -

Question 390387: My question is a quadratic equation: 8x+27=5x. I tried to solve by subtracting 8x by 5x. the 3x +27=0. I subtracted 27 and got 3x= -27. After that I got 3x= -27. My answer was x= -9. I am unsure whether this is the right method or if this is right?

It's correct. However the equation is not quadratic, since the degree is 1. It is definitely solvable by the quadratic formula (letting a = 0); it'd be kind of pointless using it though :)
