Variable Expressions Practice

A variable is a letter that represents an unspecified number. Substitute a number for each variable and perform the arithmetic operations in order to evaluate the expression.
For instance, to evaluate the expression x2 + 2x - 3y for x = 1 and y = 2, calculate the expression by substituting the given x and y:
x2 + 2x - 3y = 12 + 2×1 - 3×2 = 1 + 2 - 6 = -3.

One Step Linear Equations Practice

A one-step equation is an algebraic equation you can solve in only one step.
Most linear equations have one solution, but some equations can have no solutions or an infinity of solutions (e.g. all real numbers are solutions).
One step linear equations practice

Multi-Step Linear Equations Practice

- Simplify the expressions on each side of the equation, if necessary,
- Get all variable terms on one side and all numbers on the other side,
- Isolate the variable term to find the solution of the equation,
- Check your solution by substituting the value of the variable in the original equation.

Linear Equations with Rational Numbers Practice

In order to solve rational equations, rewrite the rational expressions in terms of a common denominator. Then, since we know the numerators are equal, we can solve for the variable.
Another way of solving rational equations is to multiply both sides of the equation by the common denominator, to eliminate the denominators. This turns the rational equation into a polynomial equation.

Multi-Step Inequalities Practice

A popular strategy for solving equations, isolating the variable, also applies to solving inequalities.
By adding, subtracting, multiplying and dividing, the inequality can be rewritten so that the variable is isolated on one side. The solutions to multi-step inequalities can be graphed on a number line.
