The solution is 4.632 because 7 doesn't go into 20 evenly. and i am not dividing
The value of the digit is 2 because the value of the 3 is 30 (tens) and if you go one place down you are in the ones
-4 | x + 5 | = -16...divide both sides by -4, eliminating it on the left side
| x + 5 | = -16/-4
| x + 5 | = 4
x + 5 = 4 -(x + 5) = 4
x = 4 - 5 -x - 5 = 4
x = -1 -x = 4 + 5
-x = 9
x = -9
solutions : x = -1 , x = -9
