**Unformatted text preview: **to find the other variable: 3x + 3 = 3 3x = 0, so x = 0 Solution is (x, y) = (0, 3) OR 5 2.1: Systems of Two Linear Equations in Two Unknowns * Elimination : term and its opposite stacked on top of each other before you add Examples : Solve each system using elimination 3. 2x + 3y = 5 and 3x + 2y = 5 4. -0.3x + 0.5y = 0.1 and 0.1x 0.1y = 0.4 5. -2x + 3y = 15 and -10x + 15y = 12 6 2.1: Systems of Two Linear Equations in Two Unknowns * No Solution-- System is Inconsistent (if a solution exists, system is consistent ) 6. 5x + 2y = 1 and -10x 4y = -2 * Infinite Solutions-- System is Redundant (one variable is arbitrary ) 7. x y = 2 and 3x 6y = 12 * All possibilities accounted for: 1 Solution No Solution Infinite Solutions...
