Q. Solve for u in terms of v, w, and x.w=v+u−xu=______
Identify Operation: Identify the operation which should be used to isolate u. Since u is added to v and subtracted by x in the equation w=v+u−x, we should subtract v from both sides and then add x to both sides to isolate u.
Subtract v: Subtract v from both sides of the equation.w=v+u−xw−v=v+u−x−vw−v=u−x
Add x: Add x to both sides of the equation to isolate u.w−v+x=u−x+xw−v+x=u
