Simplify: 2b + 7b – 5b = 10a – 4a = y + y + y = 3x + 5x = = 4x + 2y + 3x Collect like terms + 2y = 5 a – 2b + 4a – = 5 + 2y + 7y Collect like terms + 9 = 4 9a + 3b – 5a + = x + 4y + 5x – 2y Collect like terms + 2 = 14 10a – 2b + 4a + 5b + = 15 8x + 5y + 7x – 3 Collect like terms + 5 – = 7 – 8b + 4 – 8 |
