$4(x+2)=4+x+2$

$4x+8=6+x$

$4x-x=6-8$

$3x=-2$

$x=-2/3$

Verification:-

$4((-2/3)+2)=4+(-2/3)+2$

$(-8/3)+8=6+(-2/3)$

$-8+24=18-2$

$16=16$

hence LHS=RHS.

$x=-2/3$

Explanation:

$"distribute the bracket and simplify right side"$

$rArr4x+8=6+x$

$"subtract x from both sides"$

$4x-x+8=6cancel(+x)cancel(-x)$

$rArr3x+8=6$

$"subtract 8 from both sides"$

$3xcancel(+8)cancel(-8)=6-8$

$rArr3x=-2$

$"divide both sides by 3"$

$(cancel(3) x)/cancel(3)=(-2)/3$

$rArrx=-2/3" is the solution"$
