Validate IBAN structure, length, and mod-97 check digits for 80+ countries. Catch transfer typos before money moves — local ibantools work, free, no signup.
x = 5 — subtract 7 (3x = 15), divide by 3. Each isolation step displays in classroom order.
Cleared first by multiplying through by the LCD — x/2 + x/3 = 5 becomes 5x = 30. Denominators never survive step one.
Substitute back: 3(5)+7 = 22 ✓. The solver verifies automatically — do it manually on exams.
