Решение
1) (5a – 2b) – (3b – 5a) = 5a – 2b – 3b + 5a = 10a – 5b
2) (6a – b) – (2a + 3b) = 6a – b – 2a – 3b = 4a – 4b
3) 7x + 3y – (-3x + 3y) = 7x + 3y + 3x – 3y = 10x
4) 8x – (3x – 2y) – 5y = 8x – 3x + 2y – 5y = 6x – 3y
2) (6a – b) – (2a + 3b) = 6a – b – 2a – 3b = 4a – 4b
3) 7x + 3y – (-3x + 3y) = 7x + 3y + 3x – 3y = 10x
4) 8x – (3x – 2y) – 5y = 8x – 3x + 2y – 5y = 6x – 3y
1) (5a – 2b) – (3b – 5a) = 5a – 2b – 3b + 5a = 10a – 5b
2) (6a – b) – (2a + 3b) = 6a – b – 2a – 3b = 4a – 4b
3) 7x + 3y – (-3x + 3y) = 7x + 3y + 3x – 3y = 10x
4) 8x – (3x – 2y) – 5y = 8x – 3x + 2y – 5y = 6x – 3y
2) (6a – b) – (2a + 3b) = 6a – b – 2a – 3b = 4a – 4b
3) 7x + 3y – (-3x + 3y) = 7x + 3y + 3x – 3y = 10x
4) 8x – (3x – 2y) – 5y = 8x – 3x + 2y – 5y = 6x – 3y
