How many solutions does the following equation have? -4(2+5) = -4r – 20

Choose 1
A. No solutions
B. Exactly one solution
C. Infinitely many solutions

I think the answer will be C. Infinitely many solutions because if you factor out -4 on the right side of the equation, you will get -4(r + 5). By comparing both equations, r will equal to 2, and if that is the case, both equations look exactly the same, meaning that there can be more than one solution. So, C will be the best answer.

Iwould think that the correct answer is 8.1
