Our class studied about transposition, linear equation and distributive law. First, our math teacher told how to do distributive law in linear equation. For example, 4(x+1)=x-2 is x=-2. Because when we use distributive law, it becomes 4x+4=x-2. When we use transposition, it becomes 4x-x=-2-4 so it is 3x=-6. When we divide 3 to left side and right side, it becomes x=-2. I learn it in academy so I think it was easy. 답변자 ts0113 답변일 2017-05-24 답변내용 Today I will talk about what I studied during today's school math class. >> I will share about what I studied during our Math class.
