Answer:
The answer is explained below
Step-by-step explanation:
This is a word problem, therefore to solve it the statement have to be writing in form of an equation and then solved.
Let the number of fishes caught by Bryan's son be x fishes. Since Bryan caught as many fish as his son, Bryan caught x fishes
Let the number of fishes caught by Elton's son be y fishes. Since Elton caught three times as many fish as his son, Bryan caught 3y fishes
All together, they caught 25 fish
Therefore it can be represented by the equation:
x + x + y + 3y = 25
2x + 4y = 25
2x = 25 - 4y
x = (25 - 4y)/2
The number of fish caught by Bryan is half of the difference between the total fish caught and four times the number of fish caught by Elton son
Natasha's age is 81 years and Andrew's age is 31 years
Step-by-step explanation:
- Step 1: From the given details, let the age of Natasha be x, then age of Andrew is x - 50.
- Step 2: Form equations out of their details of ages 6 years ago.
⇒ x - 6 = 3(x - 50 - 6)
⇒ x - 6 = 3(x - 56)
⇒ x - 6 = 3x - 168
⇒ 2x = 162
⇒ x = 81
- Step 3: Calculate Andrew's age
x - 50 = 81 - 50 = 31
