Learn how to solve linear equations that have the variable on both sides of the equation. For example, solve 2x+5=6x-3. Also learn how to solve linear equations with expressions in parentheses. For example, 3(x-1)=9.
Solve equations by adding/subtracting numbers from both sides, or by multiplying/dividing both sides by the same number.
Solve any possible linear inequality in one variable. For example, solve -3x-7
Learn how to write proportions and how to solve proportions.
Learn how to solve equations like 2x+7=13 and 3(x+4)=3, which can be solved in two steps.
Learn how to solve more complex (mathematical) inequalities. Also learn to construct inequalities to model real-world situations.
Learn how to solve (mathematical) inequalities. A key concept in this tutorial is flipping the inequality sign when multiplying or dividing both sides by a negative number.
