Step-by-step explanation:
Expressions are arithmetical declarations that have at least two terms that contain figures or factors but which are linked by an intermediate operator. Adding, subtraction, multiplication, or division may well be the mathematical operators, and the further discussion can be defined as follows:
Given:
![\to \bold{4 -\frac{1}{2}(-8x + 6) = -5x - (-x + 10)}\\\\](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B4%20-%5Cfrac%7B1%7D%7B2%7D%28-8x%20%2B%206%29%20%3D%20-5x%20-%20%28-x%20%2B%2010%29%7D%5C%5C%5C%5C)
To find:
![\bold{x=?}\\\\](https://tex.z-dn.net/?f=%5Cbold%7Bx%3D%3F%7D%5C%5C%5C%5C)
Solution:
![\to \bold{4 -\frac{1}{2}(-8x + 6) = -5x -(-x + 10)}\\\\\to \bold{4 +\frac{8x}{2} - \frac{6}{2} = -5x +x - 10}\\\\\to \bold{4 +4x -3 = -5x +x - 10}\\\\\to \bold{4 +10 +4x +5x -x -3 = 0}\\\\\to \bold{11 +8x = 0}\\\\\to \bold{8x = -11}\\\\\to \bold{x =\frac{-11}{8}}\\\\](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B4%20-%5Cfrac%7B1%7D%7B2%7D%28-8x%20%2B%206%29%20%3D%20-5x%20-%28-x%20%2B%2010%29%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B4%20%2B%5Cfrac%7B8x%7D%7B2%7D%20-%20%20%5Cfrac%7B6%7D%7B2%7D%20%3D%20-5x%20%2Bx%20-%2010%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B4%20%2B4x%20-3%20%3D%20-5x%20%2Bx%20-%2010%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B4%20%2B10%20%2B4x%20%2B5x%20-x%20-3%20%3D%200%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B11%20%2B8x%20%20%3D%200%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B8x%20%20%3D%20-11%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7Bx%20%20%3D%5Cfrac%7B-11%7D%7B8%7D%7D%5C%5C%5C%5C)
So, the final answer is "
