Question

faith is 16 years older than precoius in 10 years time. faith will be double Precious age. How old is precious?​

Answer 1

Answer:

6 years old

Step-by-step explanation:

Let $f$ represent Faith's current age and let $p$ represent Precious's current age.

Faith is 16 years older than Precious:

$f=p+16$

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

$f+10=2(p+10)$

We can substitute the top equation into the bottom equation:

$(p+16)+10=2(p+10)$

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

$p+26=2p+20$

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

$6=p$

This means Precious is 6 years old.
