Answer:

Let me try to answer this one. Hope it will help you.

Step-by-step explanation:

y= age of Jerry

x= age of his brother

Jerry is three times as old as his brother

y=3x

four years from now, he will be two times as old as his brother.

y= 2x + 4

Let's solved!

first, find the x. kahit di na kayo!

y= 2x + 4

3x = 2x + 4

3x - -2x = 2x + 4 -2x

x=4

then, after mo sya makita , proceed to solve y.

y=3x

y=3(4)

y= 12

then finally you got it!

Age of Jerry is 12

Age of his brother is 4

wag na kayong mag tanong Basta yun na yun! Have a nice night everyone ❤️
