Answer:
4x + 15
Step-by-step explanation:
Let the age of Khairul's uncle y.
From the question given above, the following were obtained:
Khairul's age = x years
In 5 years time:
Khairul's age = x + 5
Khairul's uncle age = y + 5
But from the question given above,
Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:
y + 5 = 4(x + 5)
Clear bracket
y + 5 = 4x + 20
Subtract 5 from both side
y + 5 – 5 = 4x + 20 – 5
y = 4x + 15
Therefore, Khairul's uncle present age is 4x + 15
Answer:
Step-by-step explanation:
This problem tests our ability to express word problem using equation
Given data
Khairul age = x years
let the uncle's age be y
in five years time, Khairul will be = x+5
in five years time, the uncle will be = y+5
hence Khairul uncle's age is
y= 4(x+5)
y=4(x+5)
y=4x+20
hence the uncles current age is
y+5=4x+20
y= 4x+20-5
y= 4x+15
