Solve equation for the variable.

4e-6e-5=15

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.
