ABSOLUTE VALUE EQUATIONS #4--KEY
Directions: Absolute Value Equations typically have two solutions. For example, with the equation x  9 , x could
equal 9 or -9, because both numbers are 9 units away from zero on a number line. For the absolute value equations
below, you will have to solve two different equations to find both solutions.
Examples:
x  7  10
x + 7 = 10
or x + 7 = -10
x=3
or
x = -17
1)
2 x  12  14
2 x  4  10
2x + 4 = 10
or
x=3
or
2)
x = _1,-13 _
4)
10  5x  15
x = 12,-8
5)
x = _1,-2 _
7)
6 x  12  24
x = 2,-6
_
4 x  8  40
_
2 x  20  42
x = _31,-11 _
8)
4 x  2  30
x = _8,-7

2x + 4 = -10
x = -7
3)
3x  3  33
x = _10,-12 _
6)
x  3  71
x = _68,-74 _
9)
3  2 x  67
x = _32,-35 _
