Math Problem Statement

If 3x + 10 = 9x + 8, what is the value of x?

Solution

The image shows a math problem related to geometry, specifically dealing with triangles. The question asks for the value of xx, given the following equation:

If3x+10=9x+8,what is the value ofx?\text{If} \, 3x + 10 = 9x + 8, \, \text{what is the value of} \, x?

Solving the Equation:

To solve for xx, follow these steps:

  1. Subtract 3x3x from both sides:

    3x+103x=9x+83x3x + 10 - 3x = 9x + 8 - 3x

    Simplifying this, we get:

    10=6x+810 = 6x + 8

  2. Subtract 8 from both sides:

    108=6x+8810 - 8 = 6x + 8 - 8

    Simplifying this, we get:

    2=6x2 = 6x

  3. Divide both sides by 6:

    26=x\frac{2}{6} = x

    Simplifying this, we get:

    x=13x = \frac{1}{3}

Answer:

The value of xx is 13\frac{1}{3}.
