Compound_inequalities

Learn how to solve compound inequalities. For example, solve 2x+1>3 AND -x-5<4.

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).

Multi_step_inequalities

Solve any possible linear inequality in one variable. For example, solve -3x-7

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_with_unknown_coefficients

An equation like ax+3x=bx+5 can still be solved for x even though some of the coefficients are variables.
