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

2(x/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))

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

x=a cosec theta+b cot theta, y=a cosec theta-b cot theta . Then, ((x+y)/(a))^(2)-((x-y)/(b))^(2)=4
