Which of the following equations has infinitely many real solutions?
5x + 1 = x - 1
5(x - 5) = 5x + 25
5x + 1 = 5x - 1
5(x - 5) = 5x - 25

Which of the following equations has infinitely many real solutions?

Take a look at the last one. $$5(x-5)=5x-25$$
Multiply in the parentheses $$5x-25=5x-25$$ add 25 $$5x=5x$$ divide with 5 $$x=x$$ Here you see that x can be anything
