If `(x+y)^3=1331 and (x-y)^5=243`, then find `x^2-y^2`.

If (2x^2-y^2)^4=256 and (x^2+y^2)^5=243 , then find x^4-y^4 The following steps are involved in solving the above problem. Arragne then in sequential order. (A) (x^2-y^2)^4=256=4^4 and (x^2+y^2)^5=3^5 (B) x^4-y^4=12 (C) (x^2-y^2)(x^2+y^2)=4xx3 (D) x^2-y^2=4 and x^2+y^2=3

if (3x-2y):(5x-7y)=5:3 then, find x:y.

(i) x+2y=-7 and 3x-2y=-1, then find the value of x. (ii) If x+y=8 and 4y-x=2, then find the value of y. (iii) If 3x+5y=9 and 5x+3y=7, then find the value of x+y. (iv) If 3x-y=11 and x-3y=17, then find the value of x-y.

If |x+1|+y=5 and x-|y|=2, find x+y

If 2x+3y=34 and (x+y)/(y)=(13)/(8), then find the value of 5y+7x

If 2x +3y = 30 and (x+y)/y = 11/8 , then find the value of 5y + 6x

If (2x+y,7)=(5,y-3) then find x and y

If (2x+y,7)=(5,y-3) then find x and y

If (3x-y):x(4x+y)=5:12 then find (x^(2)+y^(2)):(x+y^(2))
