\bf 14^{x+3}=21\implies log(14^{x+3})=log(21)\implies (x+3)log(14)=log(21)
\\\\\\
x+3=\cfrac{log(21)}{log(14)}\implies x=\cfrac{log(21)}{log(14)}-3

and surely you'd know what that is.

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? How much sugar is in 50%.
sergeinik [125]
A fifty-fifty sugar-water solution would contain the same amount of water by weight as by sugar, that is, 0.5 lb water.

In other words, a solution that is made up of 0.5 lb sugar and 0.5 lb water is a 50% sugar concentration.
