Answer:

X = 2

Explanation:


\sf \: First, solve \: the \: brackets.


\sf \: 10 - 2(2x + 1) = 4(x - 2) \\ \sf10 - 4x - 2 = 4x - 8 \: \: \: \: \: \: \:


\sf \: Combine \: like \: terms .


\sf8 - 4x = 4x - 8


\sf \: Subtract \: 4x \: from \: both \: sides \: to \: remove \: 4x.


\sf \: 8 - 4x - 4x = 4x - 8 - 4x \\ \sf8 - 8x = - 8


\sf \: Subtract \: 8 \: from \: both \: sides \: to \: remove \: 8.


\sf8 - 8 - 8x = - 8 - 8 \\ \sf - 8x = - 16


\sf \: Divide \: both \: sides \: by \: -8.


\sf \: x = 2
