x^2 + 3x + 2 = x^2 + ax + 2x + 2a
Then, we bring the variable to one side and the numerical values on the other side by transposing them:
x^2 + 3x - x^2 - ax -2x - 2a = -2
By simplifying further, we get:
x - ax = -2
-x + ax = 2
Now we try to bring x to right hand side:
a = (2 + x)/x
This is the solution for a in terms of x. If you have the value of x, then you can find the value of a as well.
Hope this helps.
Allthough this answer wos incorrect it still made my brain hurt xD I've never been great at maths.
