lawrence is twice as old as his friend jerome. jerome is 8 years older than pearl. in 8 years, lawrence will be three times as old as pearl. what would be the age of jerome, lawrence and pearl.?

Sagot :

Present ages:  
Rachel: x
Jerome: x + 8
Lawrence: 2(x+8) or 2x + 16

Ages in 8 years, future (present + 8)
Rachel: x + 8
Jerome:  x + 8 + 8 or x + 16
Lawrence:  2x + 16 + 8 or 2x + 24

Equation:  In 8 years, Lawrence will be three times as old as Pearl.

2x + 24 = 3(x + 8)
3x - 2x = 24 - 24
x = 0

PRESENT AGES:
 Rachel: x = 0 age (a baby)
 Jerome: 0 + 8 = 8 years old
 Lawrence: 2x + 16= 2(0) + 24 = 16 years old

IN 8 YEARS (Present + 8)
Rachel:  0 + 8 = 8 years old
Jerome:  8 + 8 = 16 years old
Lawrence = 16 + 8 = 24 years old
