Complete the following proof.

Given: 200 = 4m + 18 – 2m

Prove: m = 91


1. 200 = 4m + 18 – 2m Given
2. 200 = 2m + 18 Combine like terms
3. 182 = 2m Addition Property
4. 91 = m Division Property
5. m = 91 Symmetric Property

I think this is correct, but I just want to double check

Your answer is correct since you followed the steps:1. 200 = 4m + 18 – 2m is the given equation
2. 200 = 2m + 18 combine like terms  200 – 18 = 2m
3. 182 = 2m Addition Property   182 = 2m
4. 91 = m Division Property   182 ÷ 2 = 2m ÷ 2
5. m = 91 Symmetric Property
