If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
What is the rule for solving equations?
The following steps provide a good method to use when solving linear equations. Simplify each side of the equation by removing parentheses and combining like terms. Use addition or subtraction to isolate the variable term on one side of the equation. Use multiplication or division to solve for the variable.
What is the golden rule for solving equations in math?
The mathematical golden rule states that, for any fraction, both numerator and denominator may be multiplied by the same number without changing the fraction’s value.
What is the first rule of solving an equation?
The addition rule for equations tells us that the same quantity can be added to both sides of an equation without changing the solution set of the equation. Adding 12 to each side of the equation on the first line of the example is the first step in solving the equation.
What are the 4 steps to solving an equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

An algebraic rule is a mathematical expression that relates two variables and is written in the form of an equation. There are many constant algebraic rules, such as area = length x width. You can also create your own rule when given a set of variables.
What is multiplication rule in algebra?
The commutative rule of multiplication states that when two terms are multiplied, the order of multiplication does not matter. The equation for the same is written as, (a × b) = (b × a). For example, (x4 – 2x) × 3x = 3x × (x4 – 2x).

What is the easiest method in solving system of linear equations Why?
Graphing. Graphing is one of the simplest ways to solve a system of linear equations. All you have to do is graph each equation as a line and find the point(s) where the lines intersect. These equations are already written in slope-intercept form, making them easy to graph.
