The sum of two mixed numbers is 2 and a half more than the difference.
What are the two numbers?
:
a + b = 2 + a - b
Subtract a from both sides
b = 2 - b
add b to both sides
2b = 2
convert to a improper fraction
2b =
divide both sides by 2
b =
Convert to a mixed number: b = 1 is one number
Find a
a + = + a -
do the math and it is apparent that a can be any value
a - a + =
