solving linear equations and inequalities worksheet pdf

Algebra simplifies the process of solving real-world problems. If you divide or multiply an inequality by a negative number, reverse the inequality to obtain an equivalent inequality. 16pt Finally, check to verify that your solution solves the original equation. Combine the solution sets for a compound inequality with "or". Subtracting $7$ from each side and dividing each side by positive $5$ results in an inequality that is true. You can choose from SEVEN basic types of equations, ranging from simple to complex, explained below (such as one-step equations, variable on both sides, or having to use the distributive property). Solve and graph the solution set: $2(4x5)<92(x2)$.
