| 1 | 2x + 6 = 12 → subtract 6: 2x = 6 → divide by 2 | x = 3 |
| 2 | 5x − 4 = 26 → add 4: 5x = 30 → divide by 5 | x = 6 |
| 3 | x⁄3 + 5 = 9 → subtract 5: x⁄3 = 4 → multiply by 3 | x = 12 |
| 4 | 6x − 2x + 1 = 13 → combine: 4x + 1 = 13 → subtract 1: 4x = 12 → divide by 4 | x = 3 |
| 5 | 3(x − 2) = 9 → distribute: 3x − 6 = 9 → add 6: 3x = 15 → divide by 3 | x = 5 |
| 6 | 4x + 9 = 1 → subtract 9: 4x = −8 → divide by 4 (watch the sign) | x = −2 |
What to look for on the paper: both-sides operations lined up, the result of each step written out, and a boxed final answer. Award credit for correct steps even if the final number slips.Qué buscar en la hoja: operaciones en ambos lados alineadas, el resultado de cada paso escrito y la respuesta final encerrada. Da crédito por los pasos correctos aunque el número final falle.
Security note: this is a client-side gate — it stops casual peeking but the answers can be read by viewing page source. For real protection on IONOS, put this file behind .htaccess Basic Auth like your PDF keys. Password is the same as the Regents Trainer; change TEACHER_PW in the source to update it.
Nota de seguridad: esta es una barrera del lado del cliente — evita el vistazo casual, pero las respuestas se pueden ver en el código fuente. Para protección real en IONOS, coloca este archivo detrás de .htaccess como tus claves en PDF. La contraseña es la misma que la del Regents Trainer; cambia TEACHER_PW en el código para actualizarla.
