Multiply through by (x-c) to get

a (x-c)/(x-a) = c-b now multiply by x-a

a (x-c) = (c-b)(x-a) expand both sides

ax - ac = cx - ac - bx + ba add ac to both sides

ax = cx - bx + ba put all of the x factors on the left

ax + bx - cx = ba factor out x on the left

x ( a+ b -c) = ba divide bt (a+b-c)

x = ba / (a+b-c) Just check my math a bit, but that is how to do it......
