Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify
</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8
the answer is
<span>you need to add 8 of a cup of the pure vinegar to the mixture</span>

Answer: x=4, x=-5
Step-by-step explanation:
Multiply everything by the LCM = (x-4)(x+5):
Simplify by cancelling out same terms: in the numerators and denominators:
(x+5)(x-4) = 0
The solution to the quadratic equation is x=4, x=-5
