Can anyone help me solve this problem; 2x + 3 = 2x + 4 - 1 and explain why there are an infinite number of solutions? Thanks!!

2x + 3 = 2x + 4 - 1

2x - 2x + 3 = 3

2x - 2x + 3 - 3 = 3 - 3

0 = 0

If , when solving an equation, the variable drops out and

1. you end up with a true statement, then there will be an infinite number of solutions, and your equation is an identity

e.g. see above

2. you end up with a false statement , then there will be no solution

e.g. 2x +3 = 2x + 5

3 = 5 , which is false

thus , no solution.
