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'.
Considering that 1 lbs =16 ounces and you need one serving (8oz) then you will make two servings so the answer is two servings hope this helps and have a nice day (:
