iv) 10a² - 15a² + 4a² - 3a² = -4a²

v) -2xyz - 3xyz + 10xyz + 5xyz - 4xyz = 6xyz

Q3) i) 9a + 10x

ii) 2x + (-5y) = 2x - 5y

iii) 4x - 5y + 3z

iv) 2a + (-4b) + 3a = 2a + 3a - 4b

= 5a - 4b

v) 6xy - 2xy + 14yz = 4xy + 14yz

vi) 3x - 5y - 2x + 6y = x + y

vii) 8x² - 11y² + 6y² - 3x² = 5x² - 5y²

viii) 9abc - 6abc + abc - bc = 4abc - bc

ix) 7x²y + 8xy² - 4x²y - 5xy = 3x²y + 8xy² - 5xy

Q4) i) 3a - 4b + 4a + 2b = a - 2b

ii) 5x + 2y - 7x + y = -2x + 3y

iii) 3ab + 2bc - 5ab + 3bc + 2ab - 5bc = 0

iv) 2x - 10y + 9y - 12x + x + y = - 11x + 0y

v) 3m- 20n + 12m - 7n - 8m + 12n = 7m + 15n
