y-3quad x=(y)/(5)(x+10)

x^(2)x2y^(3)x5x^(3)y^(2) is equal to: 10x^(2)y^(5) (b) 10x^(5)y^(2)10x^(5)y^(5)(d)x^(5)y^(5)

Simplify : (2x+y)^(5)-5y(2x+y)^(4)+10y^(2)(2x+y)^(3)-10y^(3)(2x+y)^(2)+5y^(4)(2x+y)-y^(5)

{:(3x - y = 5),(6x - 2y = 10):}

Solve by the method of elimination 2x-y=3,3x +y=7 (ii) x-y=5, 3x+ 2y = 25 (iii) (x)/(10 ) +(y)/(5) =14 ,(x)/( 8) + (y)/( 6) =15 (iv) 3(2x+y) =7xy,3 (x+3y ) =11xy (v) (4)/(x) +5y =7,(3)/(x) +4y =5 (vi) 13x +11y = 70,11x +13y =74

Find the value of x:y, if (8x-10y)/(3x+4y) = (4)/(5) .

{:(x - 2y = 8),(5x - 10y = 10):}

Show that: (x^(2)+y^(2))^(5)=(x^(5)-10x^(3)y^(2)+5xy^(4))^(2)+(5x^(4)-10x^(2)y^(3)+y^(5))^(2)
