Understand what a linear equation is and its format.
A linear equation is an equation involving only one variable. It takes the form of ax + b = c, where a, b and c are constants, and 'x' is the unknown variable. Such equations can be solved by various algebraic methods such as substitution, elimination or graphing. It's important to understand the structure of a linear equation to correctly solve it – this worksheet provides questions helping you do just that!
Substitute values for the unknown variable to solve problems.
When working with one-variable linear equations, it can be helpful to substitute values for the unknown variable to solve. This is done by replacing the x in the equation with any value (sometimes called a guess) and then calculating the result. If necessary, several more guesses may be used until the correct solution is found. By doing this, students will develop a better understanding of how equations are solved.
Identify which techniques can be used to solve linear equations in one variable.
Linear equations in one variable can be solved using the following techniques: trial and error, substitution, graphing or plotting points on a graph, factoring, solving using the distributive property, elimination using addition or subtraction and cross-multiplying.

Q: What is a linear equation in one variable?
A: A linear equation in one variable is an equation of the form ax + b = c, where a, b, and c are constants and x is the variable.
Q: What is the difference between an equation and an expression?
A: An expression is a combination of variables, constants, and operations, while an equation is a statement that shows that two expressions are equal.
Q: How do you solve a linear equation in one variable?
A: To solve a linear equation in one variable, use inverse operations to isolate the variable on one side of the equation. For example, to solve 2x + 3 = 7, subtract 3 from both sides to get 2x = 4, and then divide both sides by 2 to get x = 2.
Q: What is the solution of a linear equation?
A: The solution of a linear equation is the value of the variable that makes the equation true. For example, the solution of 2x + 3 = 7 is x = 2.
Q: How many solutions can a linear equation in one variable have?
A: A linear equation in one variable can have one solution, no solution, or infinitely many solutions.
Q: What is the slope-intercept form of a linear equation?
A: The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
Q: How do you graph a linear equation in one variable?
A: To graph a linear equation in one variable, plot the y-intercept and then use the slope to find additional points to plot. Connect the points with a straight line to graph the equation.
Q: What are word problems in linear equations?
A: Word problems in linear equations involve using mathematical equations to solve real-world problems. For example, a word problem might involve calculating how many hours it will take to travel a certain distance at a given speed.
Q: How do you translate a word problem into a linear equation?
A: To translate a word problem into a linear equation, identify the variable and write an equation that represents the relationship between the variable and the other quantities in the problem.
