Answer:
x = 1/(a-b)
Step-by-step explanation:
The given equation is ax = bx + 1
Collecting like terms:
ax - bx = 1
Factorizing x out of the equation:
x(a - b) = 1
Dividing both sides by (a - b):

Therefore, x is related to the difference of a and be by the equation
x = 1/(a-b) where a - b is the difference of a and b
