Question

Pamela's age is three times Jiri's age. The sum of their ages is 68. What is Jiri's age?

Answer 1

let p = Pamela's age
let j = Jiri's age

j+p = 68
p = 3j

solve for j

Answer 2

j=p/3

Answer 3

right?

Answer 4

p = 3j
p + j = 64
4j = 64
j = 16

Answer 5

Pamela's age = 3 x
Jiri's age = x

3 x + x = 64
4 x = 64

x = 64/4 =16

So , Jiri's age = 16 years old :-

Answer 11

start back with our two equations

j+p = 68
p = 3j

since p = 3j, we can replace "p" with "3j" whenever we see it

j + p = j + 3j = 4j = 48
solve for j

Answer 12

okay so 4j = 48 ?
