Answer 1

The student's work shows that the equation \( 2(2x+2) = 4(x+4) \) simplifies to \( 4 = 4 \), which is a true statement. This indicates that the original equation is an identity—true for all values of \( x \).

Thus, the equation solved correctly would show that it has **infinitely many solutions**.

Therefore, the student is correct in stating that the equation has infinitely many solutions.
