f) 5×-7y+4×+8y-3y-6y+5×-3y

Answer 1

a) 5×+4×-7×-3×-6×+8× = 17x - 16x = x

b)4a-2b+5a-3b-8a+6b-a = 9a - 9a -5b + 6b = b

c)×⁴-5׳-4ײ+3×+1-×⁴+5׳-3ײ-7×+3 = -7x^2 -4x +4

d) a²-4ab+b²+5a²-3ab-b² = 6a^2 + b^2 - b^2 - 7ab = 6a^2 - 7ab

e) mp-4m+5p-7mp- 7m-8p = -6mp -11m -3p

f) 5×-7y+4×+8y-3y-6y+5×-3y = 14x - 11y
