** Example 1 ** l X l = 7 X = 7 or X = -7 ** Example 2 ** l X + 3 l = 8 X = 5 or X = -11 ** Example 3 ** l X + 10 l = 4 X = -6 or X = -14 Positive: X + 10 = 4 Negative: X + 10 = -4 ** Example 4 ** 3 l X + 2l – 5 = 10 3 l X + 2 l = 15 (added five to both sides) l X + 2 l = 5 (divided both sides by 3) Positive: X + 2 = 5 (X must be 3) Negative: X + 2 = -5 (X must be -7)
