Let your age = X
Now you have 500 - 3x = 278
Subtract 500 from each side:
-3x = -222
Divide both sides by -3:
x = -222 / -3
x = 74
You are 74 years old.
The age of an old man is 74 years old.
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Let the age of an old man be x.
500 reduced by 3 times my age is 278 can be expressed as
⇒ [tex]500-3x=278[/tex]
⇒ [tex]500-278=3x[/tex]
⇒ [tex]222=3x[/tex]
⇒ [tex]x=\frac{222}{3}[/tex]
⇒ [tex]x=74[/tex]
Hence we can conclude that the age of an old man is 74 years old.
