Math Problem Statement

Los valores de x que verifican | -10 | - 8 = | -10 | | 12 - 4x | / | 60 | - 3 | * | 9 - 3x | / | -27 | son:

Solution

The problem in the image asks to solve for the values of xx that satisfy the equation:

8=10124x60393x278 = \frac{| -10 | | 12 - 4x |}{| 60 | - 3} \cdot \frac{| 9 - 3x |}{| -27 |}

Let's break it down:

Step 1: Simplify absolute values

  1. The absolute value of 10-10 is 1010.
  2. The absolute value of 6060 is 6060.
  3. The absolute value of 27-27 is 2727.

So, we can rewrite the equation as:

8=10124x60393x278 = \frac{10 | 12 - 4x |}{60 - 3} \cdot \frac{| 9 - 3x |}{27}

Step 2: Simplify further

The denominator 603=5760 - 3 = 57, so the equation becomes:

8=10124x5793x278 = \frac{10 | 12 - 4x |}{57} \cdot \frac{| 9 - 3x |}{27}

Now, multiply the two fractions:

8=10124x93x57278 = \frac{10 | 12 - 4x | | 9 - 3x |}{57 \cdot 27}

Calculate 5727=153957 \cdot 27 = 1539, so the equation becomes:

8=10124x93x15398 = \frac{10 | 12 - 4x | | 9 - 3x |}{1539}

Step 3: Solve for xx

Now, multiply both sides of the equation by 1539:

81539=10124x93x8 \cdot 1539 = 10 | 12 - 4x | | 9 - 3x |

12312=10124x93x12312 = 10 | 12 - 4x | | 9 - 3x |

Divide both sides by 10:

1231.2=124x93x1231.2 = | 12 - 4x | | 9 - 3x |

At this point, we need to solve for xx by considering the different cases for the absolute values.
