What is Algebra?
Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
At 7:00 a.m., the temperature was 12° below zero Fahrenheit.
Then the temperature rose 3° per hour for 9 hours.
Let x be the number of hours. Then the equation of temperature (T) will be
T = 3x – 12
From 7:00 a.m. to 2:00 p.m., there are 7 hours.
Then the temperature at 2:00 p.m. will be
T = 3(7) – 12
T = 21 – 12
T = 9
