Help with the SAT practice question in front of you

Use the SAT AI Solver when you are stuck on a specific SAT practice question. Paste the question, include the answer choices when they are available, or upload a clear photo of the problem. The explanation should show the reasoning behind the answer, point out the relevant skill, and help you check your own approach before moving to the next question.

One question, worked through

Why is choice B the answer to this SAT Math question and not choice D?

Both values satisfy the equation you get after squaring both sides, but the one in choice D makes the left side negative, so it is an extraneous solution. Substituting each candidate back into the original equation is the step that rules it out.

SAT Math Method explained

The reasoning behind the answer, not the letter alone.

SAT Math questions, step by step

Ask for help with algebra, advanced math, problem-solving and data analysis, geometry, or a calculator/non-calculator practice question. Include the full question and choices if there are any. A useful explanation identifies the equation, rule, graph or strategy to use, then shows how each step leads to the result.

Practice question: if 3x + 5 = 2x + 12, what is the value of x?

1 Subtract 2x from both sides to collect the variable: x + 5 = 12

2 Subtract 5 from both sides: x = 7

3 Substitute back: 3(7) + 5 = 26 and 2(7) + 12 = 26, so the answer checks

Answer x = 7

SAT Reading & Writing questions

Paste a passage, sentence or question with its answer choices to work through reading comprehension, vocabulary in context, grammar, punctuation, sentence boundaries or rhetorical synthesis. Ask why one choice fits the evidence or grammar rule better than the others, rather than relying on a letter alone.

Which choice keeps the sentence grammatical?

The results of the study, published last spring, suggest a different conclusion.

The subject is "results", not "study" — the phrase between the commas does not change what the verb has to agree with.

Solve a SAT question from a photo

Upload a readable photo of a worksheet, practice book page, graph, table or passage. Make sure the question number, answer choices and any diagram are visible. Say what you tried first so the explanation can focus on the step that is blocking you.

Use explanations to review your work

Compare the explanation with your own reasoning after you attempt the question. If your answer differs, ask which assumption, calculation or reading clue changed the result. This turns a single practice question into a review of the skill you can use on similar questions.

x^2 = 49, so x = 7

x^2 = 49, so x = 7 or x = -7

A squared variable has two roots unless the question rules one out. Read the constraint in the question before discarding the negative value.
