EXPLANATION
Assuming that the age of Sydney is x and the age of Devanghn is y, we can apply the following relationship:
(1) 52 + x = y
(2) 3x = y
Now, we have a system of equations:
Plugging in y=3x into (1):
52 + x = 3x
Subtracting -x to both sides:
52 = 3x - x
Subtracting numbers:
52 = 2x
Dividing both sides by 2:
52/2 = x
Simplifying:
[tex]26=x[/tex]Switching sides:
[tex]x=26[/tex]In conclusion, the age of Sydney is 26
