1. Problem Description

The problem asks to solve the following equation for xx:
[5x+(8+3x)19]1=1[2x+(7x65)][5x + (8 + 3x) - 19] - 1 = 1 - [-2x + (7x - 65)]

2. Solution Steps

First, we simplify the expressions within the brackets.
[5x+(8+3x)19]1=1[2x+(7x65)][5x + (8 + 3x) - 19] - 1 = 1 - [-2x + (7x - 65)]
[5x+8+3x19]1=1[2x+7x65][5x + 8 + 3x - 19] - 1 = 1 - [-2x + 7x - 65]
[8x11]1=1[5x65][8x - 11] - 1 = 1 - [5x - 65]
8x111=15x+658x - 11 - 1 = 1 - 5x + 65
8x12=665x8x - 12 = 66 - 5x
Now, we move the terms with xx to the left side and the constant terms to the right side.
8x+5x=66+128x + 5x = 66 + 12
13x=7813x = 78
Now, we divide both sides by 13 to solve for xx.
x=7813x = \frac{78}{13}
x=6x = 6

3. Final Answer

x=6x = 6
