How do you solve for x in ax-x equals c?

Answer 1

ax - x = c

Factor 'x'

Hence

x(a - 1) = c (NB '1' is ONE , not 'I'. )

Divide both sides by 'a-1'

Hence

x = c/(a-1)

Solved for 'x'.

Answer 2

ax - x = c

therefore x*(a - 1) = c

Provide a ≠ 1, divide both sides by a - 1 to give x = c/(a - 1)

If a = 1 then the value of x is indeterminate.
