Odpowiedź:
a)
4ab + (2a - 3ab + 2) = 4ab + 2a - 3ab + 2 = 2a + ab + 2
b)
-(3p - r) - 2r = -3p + r - 2r = -3p - r
c)
(3d - 8) * 4 = 12d - 32
d)
(2a - 6bc)/2 = a - 3bc
e)
2(x - 8) - 3(y - 2x²) = 2x - 16 - 3y + 6x² = 6x² + 2x - 3y - 16
-[x - (2 - x) - (5 - 2x)] - 5x = -(x - 2 + x - 5 + 2x) - 5x = -(4x - 7) - 5x = -4x + 7 - 5x = -9x + 7
