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.

To isolate a variable, you perform inverse operations to both sides of the equation until the variable is alone on one side.

x = 3

x = 9

x = 1

Multiply by -2.

A = WL.

To solve an equation means to find the value(s) of the variable(s) that make the equation true.

x = 5.

The slope-intercept form is given by $$y = mx + b$$ , where $$m$$ is the slope and $$b$$ is the y-intercept.
