Make “y” as the subject in each of the following case xa +y(a − r) = x𝑦 yx=ut+ay

Sure, let's make "y" the subject in each of the equations:

1. xa + y(a - r) = xy

First, let's isolate the terms with "y" on one side of the equation:

xy - y(a - r) = xa

Then, factor out "y":

y(x - (a - r)) = xa

Finally, divide both sides by (x - (a - r)) to solve for "y":

y = xa / (x - (a - r))

2. yx = ut + ay

First, let's isolate the terms with "y" on one side of the equation:

yx - ay = ut

Then, factor out "y":

y(x - a) = ut

Finally, divide both sides by (x - a) to solve for "y":

y = ut / (x - a)
