Question

25^x=125^x-7

Answer 1

what are you suppose to do find x

Answer 2

Simplifying
25x = 125x + -7

Reorder the terms:
25x = -7 + 125x

Solving
25x = -7 + 125x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-125x' to each side of the equation.
25x + -125x = -7 + 125x + -125x

Combine like terms: 25x + -125x = -100x
-100x = -7 + 125x + -125x

Combine like terms: 125x + -125x = 0
-100x = -7 + 0
-100x = -7

Divide each side by '-100'.
x = 0.07

Simplifying
x = 0.07
