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
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?
Hello, Sprinkledozer!
Chris is 10 years older than Josh.
Next year, Chris will be twice as old as Josh.
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: .
. . . . . and we get: .
Then Chris
