What is the value of x in the equation ? (In the picture I included)

Answer:
Step-by-step explanation:
[tex]13x-\dfrac{1}{2}(4x + 50) = 8x - 1\\\\13x -\dfrac{1}{2}*4x - \dfrac{1}{2}*50 = 8x - 1[/tex]
13x - 2x - 25 = 8x - 1
11x - 25 = 8x - 1
11x = 8x - 1 + 25
11x = 8x + 24
11x- 8x = 24
3x = 24
x = 24/3
x = 8
