Let s be the age of Mr. Silvester and w be the age of his wife

s-5= w

s-5 = (4/3)(w-5)

Hence

w = (4/3)w - 20/3

-(1/3)w = -20/3

w = 20, s=25 - Mar 4th 2013, 02:45 PMSprinkledozerRe: Solving Applied Problems (word problem)
I thought I was over this, but apparently not. I have completed all the rest of the hw without a bother, but when it comes to these word problems, I don't know how to form the problem. Here's another one: Chris is 10yr older than Josh. Next year, Chris will be twice as old as Josh. What are their ages?

So then...

Chris = (J+10) -1

Josh = (C/2) -1

How do I write the equation? - Mar 4th 2013, 03:18 PMSorobanRe: Solving Applied Problems (word problem)
Hello, Sprinkledozer!

What are their present ages?

We can solve this with one variable, one equation.

Let = Josh's age (now).

Then Chris' age is

Next year, they both will be one year older.

Chris will be

Josh will be:

Solve the equation: .

Then Chris
