Answer:
Ilan lahat Ang kabuuang bilang ng mga nakalarawang bagay
X + 5 = 3
Subtract both sides by 5
X = (-2)
Replace x in the equation with -5 and solve.
5(-5) +40 = -25 + 40 = 15
306 is the total cards sent by all the students in the class. Lets say x is the number of students in class, therefore each student needs to send x-1 cards (since they do not send themselves a card). So depending on your level of math, you could either take the complex way to solve it using quadratic equations, or just find the number that if multiplied by itself then subtracted, gives you 306.

===============
Complex way

So a = 1, b = -1, c=-306
using the quadratic equation:
