Answer 2

Answer 3

first of all multiply \(2\) with whats inside the parenthesis: \(4x-2x-2=3x+10\)

then, add the characters who include \(`x`\) together: \( 2x-2=3x+10 \)

take the two to the other side: \( 2x=3x+12 \)

take the \(`-3`\) to the other side: \(-x=12\); change the sign and you get \( \boxed{ x=-12 } \)
