difference between the ages of two cousins is 4 years. if the sum of thier ages is 42 years. how can i found their ages?
--------------------------------------
One cousin is "x" years old; the other is x+4 years old.
--------------
EQUATION:
x + (x+4) = 42
2x = 38
x = 19 yrs old (one of the cousins)
x+4 = 23 yrs old (the other cousin)
