6 years old

Step-by-step explanation:

Let represent Faith's current age and let represent Precious's current age.

Faith is 16 years older than Precious:

In 10 years' time, Faith will be double Precious's age:

We can substitute the top equation into the bottom equation:

We can combine like terms on the left side and expand out the right side:

We can subtract p from both sides, and then subtract 20 from both sides to get:

This means Precious is 6 years old.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
