For the equation m + 3 = m + 4 , can you substitute a value for m to make this a true number sentence? Make sure to explain your answer.

Answer 1

No, it is not possible to substitute a value for m that would make the equation m + 3 = m + 4 a true number sentence.

This is because in the equation, both sides start with m. Whatever value we substitute for m, it will remain the same on both sides. So the equation will always remain the same, regardless of the value of m. Adding 3 to m on one side of the equation and adding 4 to m on the other side will not change the fact that both sides are equal to each other. Therefore, there is no value of m that will make this equation true.
