[" (iii) "4x+(y)/(3)=(8)/(3),(x)/(2)+(3y)/(4)=-(5)/(2)],[" (iv) "8x-9y=6xy,10x+6y=19xy]

Solve for x and y:8x-9y=6xy,10x+6y=19xy

6x+3y=6xy; 2x+4y=5xy

(x^(2))/(4)-3xy^(3)+9y^(6)

List of the like terms in the following expression. (i) 4x^(4),-7x^(3),8x^(2),12x^(3),-9x^(4),-5x,4x^(3),12x^(2) (ii) 5xy,-3x^(2)y,2xy^(3),-2x^(2)y^(2),5x^(2)y,-3xy,6x^(2)y^(2)

Add the following (8)/(5)x+(11)/(7)y+(9)/(4)xy,-(3)/(2)x-(5)/(3)y-(9)/(5)xy

Add: (i) 3x, 7x (ii) 7y, -9y (iii) 2xy, 5xy, -xy (iv) 3x, 2y (v) 2x^(2), -3x^(2), 7x^(2) (vi) 7xyz, -5xyz, 9xyz, - 8xyz (vii) 6a^(3) , - 4a^(3), 10 a^(3), - 8a^(3) (viii) x^(2) - a^(2), -5x^(2) + 2a^(2), -4x^(2) + 4a^(2)

The following are the steps involved in factorizing 64 x^(6) -y^(6) . Arrange them in sequential order (A) {(2x)^(3) + y^(3)} {(2x)^(3) - y^(3)} (B) (8x^(3))^(2) - (y^(3))^(2) (C) (8x^(3) + y^(3)) (8x^(3) -y^(3)) (D) (2x + y) (4x^(2) -2xy + y^(2)) (2x - y) (4x^(2) + 2xy + y^(2))

Find the following products: (6x)/(5)(x^(3)+y^(3)) (ii) xy(x^(3)-y^(3))0.1y(0.1x^(5)+0.1y)( iv) (8)/(27)xyz((3)/(2)xyz^(2)-(9)/(4)xy^(2)z^(3))

Simplify : 7x^(3)+8y^(3)-(4x+3y)(16x^(2)-12xy+9y^(2))
