Math Problem Statement

-|10x + 11| = -2

Solution

The equationThe provided equation is provided: in
the\ image[

  • |10x + 11| = -2 ]

Step-by-Step is Solution:

  1. Simplify the equation: Divide both sides by 1-1 to eliminate the negative sign:

10x + 11| = 2$$

  1. Interpret the absolute value equation: Absolute value equations can be written as two separate equations: \ [10x+11=2and-  ⁣quad1010x+11=2x[ 10x + 11 = 2 \quad \text{and-}|\ \!quad 1010x + 11 = -2 x

  2. Solve each case +:

    • Case 111:| = ( -2 10\x +]

###11 Step =-by -step2 solution:

. ** SubEltractiminate the negative sign11** from both sides: : 10x=910x = -9 Divide by 10: x=910x = -\frac{9}{10}

  • Case 2: 10x+11=210x + 11 = -2
    Subtract 11 from both sides: 10x=1310x = -13 Divide by 10: xMultiplybothsidesoftheequation=byx Multiply both sides of the equation = by -1(tomakethelefthand sidepositivefrac):\[{!10x+1311=2 (to make the left --hand\ side positivefrac): \[ |\{!10x + 1311| = 2

2.}{ Interpret the absolute10 value: The absolute value equation splits} into two cases:

  • 10x+11=210x + 11 = 2
  • (10 \x]
  • 11 = -2\4)
  1. .Solve each case:
    • ** Case 1: (10Finalx + 11 Answer =:** The2 solutions\ are) : \ [ \ [ x10 =x - = \2frac -{9}{10}, -\frac 11 { 13 }{] 10 $$} 10 x = \ -]
