what is the value of x?
Z
Z
Linear equation — let's isolate x step by step.
STEP 1 · Expand
2x + 6 = 4x − 10
STEP 2 · Move x terms together
6 + 10 = 4x − 2x
STEP 3 · Simplify
16 = 2x
ANSWER
x = 8

Why Si Math AI

Better than the alternatives.
For one reason.

Everything else is general-purpose. Si Math AI is built for one thing: getting you ready for SAT, ACT, and EST.

VS ChatGPT
A brilliant assistant — for everything.
Solves your question, then forgets it. No exam scoring, no weakness tracking, no mock exams, no plan. Every chat starts from scratch.
Si Math AI gives you SAT/ACT/EST-specific solutions, persistent weakness tracking, auto-generated focus practice, and full timed mocks — all in one place.
VS Generic AI Tools
Photomath, Symbolab, & co.
Solve one problem at a time. No idea what you're studying for, no memory of your past mistakes, no Arabic / Franco support.
Si Math AI gives you A tutor that knows you're prepping for the SAT, remembers every wrong answer, explains in Arabic, English, or Franco, and recommends what to study next.
VS Private Tutors
Effective — but expensive and slow.
Available a few hours a week. Costs thousands per term. Doesn't track your weak topics between sessions. You wait days to ask the next question.
Si Math AI gives you A tutor that's online 24/7, costs a fraction of a private session, never forgets a weak topic, and answers in seconds.
VS Question Banks
Khan Academy, Magoosh, prep books.
Thousands of questions and a generic syllabus. No personalized plan. You finish a section having no idea where you actually stand.
Si Math AI gives you A personalized study plan from your real weak spots, mock exams with raw→scaled scoring, and a predicted test-day score that updates as you learn.
