Remove the brackets: after carefully observing the equation, first remove the brackets in the equation, then remove the brackets, and finally remove the braces; ?
Moving terms: move all the unknown terms in the equation to the other side of the equation, and move all the remaining terms to the other side of the equation; ?
Merging similar terms: by merging the same terms in the equation, the equation is transformed into the form of ax=b(a≠0); ?
Change the coefficient to 1: divide the two sides of the equation by the unknown coefficient a, and the coefficient before x becomes 1 to get the solution of the equation.
Extended data:
One-dimensional linear equation refers to an equation with only one unknown number, the highest order of which is 1, and both sides are algebraic expressions. A linear equation with one variable has only one root. One-dimensional linear equation can solve most engineering problems, travel problems, distribution problems, profit and loss problem, integral table problems, telephone billing problems and digital problems.
An integral equation (such as) can be simplified into a linear equation of one variable according to the properties of the equation, and it also belongs to a linear equation of one variable. A one-dimensional linear equation is a linear equation with only one root.
