Write Two Equations
Write two equations from this absolute value equation:
| 2x | = 10
2x = 10, 2x = -10
Get the absolute value by itself (you do NOT need to solve it):
|2m + 2| + 5 = 12
|2m + 2| = 7
|−2r − 1| = 11
Solve for x
3(2x + 10 ) = -36
x = -11
Write two equations from this absolute value equation:
|4x + 5| = -11
4x + 5 = -11, 4x + 5 = 11
Get the absolute value by itself (you do NOT need to solve it):
|3x - 19| - 10 = 38
|3x - 19| = 48
|−6m| = 30
m = {-5, 5}
Solve for x
3(x - 4) = 12x - 8 + 3x
x = -1/3
Write two equations from this absolute value equation:
|-9x - 10| = 14
-9x - 10 = 14. -9x - 10 = -14
Get the absolute value by itself (you do NOT need to solve it):
|5k| - 28 = 32
|5k| = 60
abs(n/3) = 2
n = {-6, 6}
What is a factorial?
The product of a positive integer and every positive integer before it.
example:
5! = 5 x 4 x 3 x 2 x 1 = 120
Write two equations from this absolute value equation:
| -19x + 8 | = -34
-19x + 8 = -34, -19x + 8 = 34
Get the absolute value by itself (you do NOT need to solve it):
3| 5m + 1| = 81
|5m+1| = 27
|v + 8| − 5 = 2
v = {-1, -15}
Give an example of an irrational number
pi, sqrt(2). etc
abs(x/4+19)=3
x/4+19=3, x/4+19=-3
Get the absolute value by itself (you do NOT need to solve it):
2|7k + 6| - 20 = 14
|7k + 6| = 17
− 5 |5m − 5| + 2 = −73
m = {-2, 4}
Solve for x
x/5 = -x + 3/25
x = -1/2
