If x = - 2 is the root of the equation - ax + B = - 1 - 2x, what is the value of the algebraic expression 4A + 2B + 1

If x = - 2 is the root of the equation - ax + B = - 1 - 2x, what is the value of the algebraic expression 4A + 2B + 1

eleven
From x = - 2, it is the equation - ax + B = - 1-2x
We get 2A + B = 5
4a+2b+1=11
