... x: dogs in the shelter y: cats in the shelter Step 2: Write a system of equations. The total number of animals in the shelter is 40, so we know x + y = 40. Because there are 10 more dogs than cats, we also know that x – y = 10. x + y = 40 x – y = 10 Copyright © 2009 Pearson Education, Inc. Publishin ...

Systems of Linear Equations and Inequalities

... system of two linear equations can have one solution, an infinite number of solutions, or no solution. • If a system has at least one solution, it is said to be consistent. The graphs intersect at one point or are the same line. • If a consistent system has exactly one solution, it is said to be ind ...

Chapter 7: Solving Systems of Linear Equations and Inequalities

... equations is an ordered pair of numbers that satisfies both equations. A system of two linear equations can have 0, 1, or an infinite number of solutions. • If the graphs intersect or coincide, the system of equations is said to be consistent. That is, it has at least one ordered pair that satisfies ...
