Answer:
x=20
Step-by-step explanation:
We want to isolate the variable x.
First, we multiply both sides by 2 to get
(x-2)=18
Next, we add 2 to both sides, which gives us,
Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.
43 1/2
28/8 * 12/1
= 348/8
