Solve the following system of equations : (2x)/(a)+(y)/(b)=2, (x)/(a)-(y)/(b)=4:

Solve the following equations: (2x)/(a)+(y)/(b)=2" and "(x)/(a)-(y)/(b)=4

Solve the following system of equations by using the method of substitution: (2x)/(a)+(y)/(b)=2,quad (x)/(a)-(y)/(b)=4

Solve the following system of equations by using the method of substitution: (2x)/a+y/b=2,\ \ \ \ x/a-y/b=4

If (x+iy)^(1/3)=a+ib,x,y,ab in R. Show that (x)/(a)+(y)/(b)=4(a^(2)-b^(2))( ii) (x)/(a)-(y)/(b)=2(a^(2)+b^(2))

Factorize each of the following algebraic expressions: (1) (x-y)^2+(x-y) (2) 6(a+2b)-4(a+2b)^2 (3) a(x-y)+2b(y-x)+c(x-y)^2 (4) -4\ (x-2y)^2+8(x-2y)

If (x+i y)^(1//3)=a+i b ,x ,y ,a b in Rdot Show that x/a+y/b=4(a^2-b^2) (ii) x/a-y/b=2(a^2+b^2)

If x=2\ \ and y=4, then (x/y)^(x-y)+\ (y/x)^(y-x)= (a) 4 (b) 8 (c) 12 (d) 2
