Question

Rearranging x+y-xr solve for y

Answer 1

The value of y = x(r -1)

Given expression is : x+y-xr

Now, on rearranging the terms of the expression we get,

x -xr + y
Now, we put it equal to zero to find the value:

x -xr + y = 0
⇒ y = xr -x (The signs changes on moving from left-hand side of the equation to the right hand side)
⇒ y = x(r -1)
