AlgebraQuestion 7 of 15

If 5x − 3 = 22, what is the value of x?

Ax = 4
Bx = 5 ✓
Cx = 6
Dx = 7
AI TutorPRO

After answering: Algebra · Q7

Why is B correct and not D?
AI Tutor

Good question. D fails because substituting x = 7 gives 5(7) − 3 = 32, not 22. B gives 5(5) − 3 = 22 ✓. Always substitute back to verify.

Frequently Asked Questions

Is myScoreBooster really free?
Yes — the core app is free with no credit card required. Four topic sessions (Algebra, Advanced Math, Standard English Conventions, and Craft & Structure), instant explanations, and your progress roadmap are all free. Upgrade to Pro to unlock all 8 topics, the full-length practice test, and AI tutor explanations.
Does it cover the Digital SAT format?
Yes. All practice is built around the current Digital SAT — two Reading & Writing modules and two Math modules, adaptive difficulty between modules, and a scaled 400–1600 score on full-length tests.
How is this different from Khan Academy SAT prep?
Khan Academy is excellent for video lessons and official practice. myScoreBooster is built for active, coached practice: targeted question sessions by topic, an adaptive roadmap that highlights your weak spots, short sessions with instant feedback — and an AI tutor that answers your specific questions in real time, something you won't get from videos.
Does it support extended time accommodations?
Yes. Full-length practice tests include both 50% extended time and 100% extended time modes, matching the accommodation approvals issued by College Board for students with IEPs or 504 plans.
What can the AI tutor actually do?
After you answer any question in a topic session, a chat drawer opens and you can ask follow-up questions — "why is that the right answer?", "show me the algebra step by step." The AI tutor knows the exact question you just answered, so its explanations are specific, not generic. After a full practice test, tap "Coach me on my mistakes" for a skill-by-skill breakdown. AI tutor is a Pro feature.
Can I prep for both the SAT and ACT?
Yes. One Pro pass covers both exams — switch between SAT and ACT anytime from your dashboard with a single tap.
