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.

2/3 = 4/6
1 = 6/6
6/6 - 4/6 = 2/6
80% = 6 in
100%=?
100/x 80/6 (proportional relationship)
then cross multiply
600 = 80x
600/80= 7.5
x=7.5
Answer:
Step-1 : Multiply the coefficient of the first term by the constant 1 • -8 = -8
Step-2 : Find two factors of -8 whose sum equals the coefficient of the middle term, which is -18 .
-8 + 1 = -7
-4 + 2 = -2
-2 + 4 = 2
-1 + 8 = 7
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2 • (x2 - 18x - 8)
| - 4 | = 4
Thus :
f ( | - 4 | ) = f ( 4 )
f ( 4 ) = ( 4 )^2 - 2(4) + 4
f ( 4 ) = 16 - 8 + 4
f ( 4 ) = 16 + 4 - 8
f ( 4 ) = 20 - 8
f ( 4 ) = 12
