GED® Algebra: Skills Hardening & Challenge Practice
A high-difficulty challenge course that hardens your algebra. It assumes you already know how to solve equations, inequalities, functions, and systems, and trains you to handle them under test-day pressure: long multi-step chains, mixed topics in one problem, sign and distribution traps, no-solution and infinitely-many cases, and word problems that hide the equation. Every practice answer is worked step by step and names the trap most students fall into.

"Hardening" a skill means making it survive pressure. You already know the moves. This course removes the scaffolding: longer chains, uglier numbers, and traps placed …

Most "hard" algebra errors are really sign errors. A subtraction sitting in front of a group is a multiplication by \(-1\). Example 1:. Distribute \(-3\) …

When the arithmetic gets heavy, convert it to integers immediately. Multiply every term by the LCD (for fractions) or a power of 10 (for decimals). …
Open trial session →Hard equations sometimes have the variable disappear. What is left tells you everything. If the remaining statement is true (like \(7=7\)), every value works: infinitely …

Inequalities follow equation rules with one extra rule: multiplying or dividing by a negative flips the inequality sign. Example 1:. Distribute:. Subtract 6:. Divide by …
Open trial session →Function notation is just substitution. \(f(3)\) means "replace every \(x\) with 3." Hardened problems nest these or ask for a combination. Example 1:. Substitute carefully, …

For systems, pick the method that makes the numbers clean: substitution when one variable is already isolated, elimination when coefficients line up. Example 1 - …

The hardest GED® algebra is usually a word problem where you must build the equation yourself. Name the unknown, translate each phrase, then solve. Example …
