Solving Systems of Linear Equations by Graphing and Substitution
Question | Answer |
---|---|
Solve the following system by substitution. 2x – 3y = –2 4 x + y = 24 | No solution (inconsistent system) |
Solve by substitution. x + 4y = 19 x – 2y = 1 | The solution is (7, 3). |
Solve by substitution. 7x + 3y = 68 x – 4y = –8 | The solution is (8, 4). |
Solve by substitution. –0.5x + y = 1.5 0.8x – 0.2y = 6.0 | The solution is (9, 6). |
Solve by substitution. x + 3y = 25 4x + 5y = 9 | The solution is (–14, 13). |
Solve by substitution. y = 4x – 10 y = 5 – x | The solution is (3, 2). |
Solve by substitution. x + y = 9 y = 3x + 1 | The solution is (2, 7). |
Solve by substitution. x = y– 2 y = 10 – 3x | The solution is (2, 4). |
