Answer:
Algebraic Equation:
2x - 10 = 4 (x - 10)
Step by step explanation:
let x be the age of Ronnick and y for Ronnel
then according to the question
x=2y -equation1
x−10=4(y−10) -equation2
from equation1 and equation2
2y−10=4y−40
2y=30
y=15years
putting value of y in equation 1
x=2y=2×15=30 years
Present age of Ronnel = 30years
Present age of Ronnick = 15 years
ten years ago...
30 - 10 = 20 years - age of Ronnel
15 - 10 = 5 years - age of Ronnick
Checking:
The age of Ronnel is twice as Ronnick
x = 2y
30 = 2(15)
30 = 30 ✓
10 years ago, Ronnel is four times as old as Ronnick
x = 4y
20 = 4(5)
20 = 20 ✓
