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

Solve by cross - multiplication : 2x + 3y = 6 and 6x - 5y = 4 .

The number of solutions of the system of equations 2x+y=4, x-2y=2, 3x+5y=6 is

4x-2y=3 6x-3y=5

Add the algebraic expressions: 4x y^2-7x^2y ,\ 12 x^2y-6x y^2,\ -3x^2y+5x y^2

Factorise by grouping method : x(6x - 5y) - 4(6x - 5y)^(2)

Solve the following system of equations by matrix method : 5x+7y+2=0 4x+6y+3=0 5x+2y=3 3x+2y=5 3x+4y-5=0 x-y+3=0 3x+y=19 3x-y=23 3x+7y=4 x+2y=-1 3x+y=7 5x+3y=12

Subtract: 6x^3-7x^2+5x-3 from 4-5x+6x^2-8x^3 x^3+2x^2y+6x y^2-y^3 from y^3-3x y^2-4x^2y

Subtract: 6x^3-7x^2+5x-3 from 4-5x+6x^2-8x^3 x^3+2x^2y+6x y^2-y^3 from y^3-3x y^2-4x^2y

{:(3x - y = 2),(6x + 2y = 4):}

{:(3x - y = 2),(6x + 2y = 4):}
