Answer: hay 16 vagones de pasajeros y 48 de carga
Step-by-step explanation:
4e - 6e - 5 = 15
Begin by combining like terms:
4e - 6e = -2e.
The equation is now simplified.
Now, it is time to find the value of the variable.
-2e - 5 = 15
Step 1: Add 5 to both sides.
We now have -2e = 20.
Step 2: Divide both sides by -2 to isolate the variable.
-2e / 2 = e; 20 / -2 = -10.
Therefore, e = -10.
