Solutions of one-dimensional linear equations

There are five steps to solve a linear equation with one variable, namely, denominating, removing brackets, shifting terms, merging similar terms, and the transformation coefficient is 1.

For example: (x+3)/6=(x+7)/ 10.

Solution: 10*(x+3)=6(x+7)

10x+30=6x+42

10x-6x=42-30

4x= 12

x=3
