No, it is not possible to substitute a value for m to make the equation m+3 = m+4 a true number sentence.
This is because when we subtract m from both sides of the equation, we are left with 3 = 4. However, 3 and 4 are not equal to each other, contradicting the statement. Thus, regardless of the value of m, this equation will always be false.
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.
