Name________________________ 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 _ www.imathworksheets.com 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 _
