Răspuns:
Explicație pas cu pas:
8a + 8b = 8(a + b)
_________
15a - 7a = a(15 - 7)
_________
6x + 6y - 6z = 6(x + y - z)
_________
50a - 25a = 25a(2 - 1)
_________
3x + 5x - 2x = x(3 + 5 - 2)
__________
12a - 16b = 4(3a - 4b)
_________
18x - 12z + 24t = 6(3x - 2z + 4t)
_________
9x + 9y + 9z - 9a = 9(x + y + z - a)
_________
5x + 10y - 15a = 5(x + 2y - 3a)
_________
18a - 27b = 9(2a - 3b)
__________
8xy - 8xz = 8x(y - z)
__________
