Extended data

Five steps to solve a linear equation with one variable;

First, the denominator

Practice: multiply each term on both sides of the equation by the least common multiple of each denominator;

Basis: Attribute II of the equation

Second, remove the brackets.

Generally, the brackets are removed first, then the brackets are removed, and finally the braces are removed, according to the law of multiplication distribution (remember to change the number if there is a minus sign or a division sign outside the brackets).

Fundamentals: laws of multiplication and distribution
