Задание №2. Приведи подобные слагаемые. 1) 5x + 3x-2x = 2) 4a-6+a+ 8 = 3) 7y-5-2y + 1 = 4) -b+2c+4b - c = 5) 3m+8-m+4= 6) 6n-9+2n-5 = 7) 4p+2q-p+ 3q = 8) 7r-8-3r+ 12 =

Пошаговое решение:

• 1) \( 5x + 3x - 2x = (5 + 3 - 2)x = 6x \)
• 2) \( 4a - 6 + a + 8 = (4a + a) + (-6 + 8) = 5a + 2 \)
• 3) \( 7y - 5 - 2y + 1 = (7y - 2y) + (-5 + 1) = 5y - 4 \)
• 4) \( -b + 2c + 4b - c = (-b + 4b) + (2c - c) = 3b + c \)
• 5) \( 3m + 8 - m + 4 = (3m - m) + (8 + 4) = 2m + 12 \)
• 6) \( 6n - 9 + 2n - 5 = (6n + 2n) + (-9 - 5) = 8n - 14 \)
• 7) \( 4p + 2q - p + 3q = (4p - p) + (2q + 3q) = 3p + 5q \)
• 8) \( 7r - 8 - 3r + 12 = (7r - 3r) + (-8 + 12) = 4r + 4 \)

Ответ:

• 1) \( 6x \)
• 2) \( 5a + 2 \)
• 3) \( 5y - 4 \)
• 4) \( 3b + c \)
• 5) \( 2m + 12 \)
• 6) \( 8n - 14 \)
• 7) \( 3p + 5q \)
• 8) \( 4r + 4 \)
