If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.
If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)
If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
Step-by-step explanation:
2(heads) + 2(goats) = 140
Heads are given, so we get:
2(52) + 2(goats) = 140
104 + 2(goats) = 140
2(goats) = 36
goats = 18
Since we know the number of goats, we know the number of chickens.
34Chickens and 18 goats.
