Answer:
x = ![\frac{ab}{a-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bab%7D%7Ba-1%7D)
Step-by-step explanation:
Given
a(x - b) = x ← distribute parenthesis on left side
ax - ab = x ( subtract x from both sides )
ax - x - ab = 0 ( add ab to both sides )
ax - x = ab ← factor out x from each term on the left side
x(a - 1) = ab ← divide both sides by a - 1
x = ![\frac{ab}{a-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bab%7D%7Ba-1%7D)
