​

Answer 1

Answer: Simplifying

4x = 4x

Add '-4x' to each side of the equation.

4x + -4x = 4x + -4x

Combine like terms: 4x + -4x = 0

0 = 4x + -4x

Combine like terms: 4x + -4x = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

Answer 2

infinitely many, because x can be anything and the equation will still be valid
