Solving one variable linear equations

Front

What is a linear equation in one variable?

Back

A linear equation in one variable is an equation that can be expressed in the form ax + b = 0, where a and b are constants and x is the variable.

Front

How do you isolate a variable in an equation?

Back

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

Front

How do you check if your solution to a linear equation is correct?

Back

You substitute the solution back into the original equation to see if both sides are equal.

Front

What is the significance of the equation 1/6 x = 15 in a word problem?

Back

What is the role of constants in linear equations?

Back

Constants are fixed values that do not change and can affect the position of the line represented by the equation on a graph.
