difference. The larger number is 6 more than twice the
smaller. Find the numbers.
Graphical Method
Two equations and their graphs are given. Find the intersection point(s) of the graphs by solving the system.
Solving a System of Equations
Solve the system, or show that it has no solution. If the system has infinitely many solutions, express them in the ordered-pair form given in Example 6
A biologist has two brine solutions, one
containing 5% salt and another containing 20% salt. How
