A student concluded that

8x-12=4(0.5x-6)

has infinitely many solutions. Which statement BEST describes the student’s conclusion?

• The conclusion is incorrect because the equation has no solution.

• The conclusion is incorrect because there is exactly one solution to the equation.

• The conclusion is correct because there are exactly two solutions to the equation.

• The conclusion is correct because when simplified, both sides of the equation are equivalent.
