Solving Linear Equations

A linear equation is an equation of the first degree, meaning it has no exponents greater than one. It can be written in the form of $$ax + b = 0$$ , where $$a$$ and $$b$$ are constants.

The solution to a linear equation is the value of the variable that makes the equation true.

$$x = -117$$

$$x = 3$$

$$x = 1$$

$$x = -2$$

$$x = -4$$

The first step is to isolate the variable on one side of the equation, often by adding or subtracting terms.

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power to simplify the equation.

Isolating a variable means rearranging the equation so that the variable is on one side and all other terms are on the opposite side.
