Solving equations
Heads up! This course may be archived and/or unavailable.
Learn how to solve linear equations that contain a single variable. For example, solve 2(x+3)=(4x-1)/2+7.
This course contains 11 segments:
Algebraic equations basics
Explore what it means for equations with variables (algebraic equations) to be solved.
Why we do the same thing to both sides of an equation
A high-level, conceptual walk-through of what an equation represents and why we do the same thing to both sides of it
One-step addition & subtraction equations
Solve equations by adding and subtracting numbers from both sides.
One-step multiplication & division equations
Solve equations by multiplying and dividing numbers from both sides.
Two-steps equations intro
Learn how to solve equations like 2x+7=13 and 3(x+4)=3, which can be solved in two steps.
Two-step equation word problems
Learn how to set up and solve equations to find answers to real-world questions.
Linear equations with variables on both sides
Learn how to solve linear equations that have the variable on both sides of the equation. For example, solve 2x+5=6x-3.
Linear equations with parentheses
Learn how to solve linear equations with parentheses using the distributive property. For example, solve -9 - (9x - 6) = 3(4x + 6).
Analyzing the number of solutions to linear equations
Linear equations can either have a single solution, infinite solutions, or no solutions. Learn how to determine the number of solutions to a given equation, and how to create equations with a desired number of solutions.
Linear equations word problems
Solve word problems by creating linear equations and solving them.
Linear equations with unknown coefficients
An equation like ax+3x=bx+5 can still be solved for x even though some of the coefficients are variables.
