Answer:
its a =y+z/w-x
Explanation:
First, subtract
z and a w from each side of the equation to isolate the
a terms while keeping the equation balanced
than factor a A from each term on the left side of the equation
now divide each side of the equation by x-w to solve for a while keeping the equations balanced
you then multiply the right side of the equation by a form of 1 to rewrite the expression as
a=-1/-1 x -y & -z/ \-x/-w
than you remove the ones add a addition to y and the z and then you flip the x and the why and add multiplication
