SOLUTION
GIVEN
A while back, either James borrowed $12 from his friend Rita or she borrowed $12 from him, but he can’t quite remember which. Either way, he is planning to pay her back or ask that she pay him back this afternoon.
He has $42.80 in his wallet,
TO DETERMINE
The equation represents the amount of money he may have after he sees Rita
EVALUATION
Let x be the money James sees after Rita
Case : 1
If James borrowed $12 from his friend Rita then James have to pay it
In this case James have = x - 12
So in this case the equation is
x - 12 = 42.80
Case : 2
If Rita borrowed $12 from James then James will receive from Rita
In this case James have = x + 12
x + 12 = 42.80
Thus both equations can be rewritten as
x - 42.80 = 12
x - 42.80 = - 12
Combining both we can write
