Real Life Scenario
Miguel has a rock collection of 30 rocks.
Most of his collection consists of igneous
rocks. There are 15 igneous rocks. The rest
are metamorphic and sedimentary rocks.
What could the possible number of
metamorphic and sedimentary rocks be?
x + 15 + y = 30

What could the possible number of
metamorphic and sedimentary rocks be?
x + 15 + y = 30
In your head think:
•What are some strategies you might try?
•What do the variables (x and y) used in the
problem represent?
•Is there more than one solution to the problem?
