A solution to a system of equations must satisfy each equation in the system. It follows that if ^x,yh is a solution to the system, the point ^x,yh lies on the graph in the xy-plane of each equation in the system. According to the graph, the point ^x,yh that lies on the graph of each equation in the system 4,1 4,1 is ^ h. Therefore, the solution to the system is ^ h. It follows that the value of x is 4.</p>","correct_answer":["4"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[],"attribution":{"source_id":"cb_practice_pdf","source_name":"College Board full-length SAT practice tests (PDF)","rights_holder":"College Board","canonical_url":"https://satsuite.collegeboard.org/practice/practice-tests/paper","retrieved_from":"https://satsuite.collegeboard.org/practice/practice-tests/paper","attribution":"Full-length SAT practice tests 4–11 © College Board, published free at satsuite.collegeboard.org.","disclaimer":"Extracted from PDF layout: equations, figures and tables do not survive intact.
