6x + 1 = 4x + 19
First, subtract '1' from both sides.
Second, subtract '19 - 1' to get '18'.
Third, subtract '4x' from both sides.
Fourth, subtract '6x - 4x' to get '2x'.
Fifth, take the '2', leaving the 'x' by itself and divide both sides.
Sixth, since '18 ÷ 2 = 9', simplify the fraction to '9'.

Answer:
x = 9
