Answer 3

I can help you with math problems. To simplify the expression m + 3 - (2m - 5), you need to follow these steps:

- First, apply the distributive property of subtraction to the parentheses. This means that you need to multiply the negative sign by each term inside the parentheses. You will get m + 3 - 2m + 5. - Next, combine the like terms. The like terms are the ones that have the same variable or are constants. In this case, you have m and -2m as like terms, and 3 and 5 as like terms. You will get -m + 8. - Finally, write the simplified expression in the standard form, which is to put the variable term first and then the constant term. You will get -m + 8.

The simplified expression is -m + 8. You can check your answer by substituting any value for m and seeing if the original expression and the simplified expression give the same result. For example, if you let m = 2, then the original expression is 2 + 3 - (2*2 - 5) = 6, and the simplified expression is -2 + 8 = 6. They are equal, so the answer is correct.
