Explanation:
First step is to distribute the bracket.
#rArr3x+18=-3# Leave 3x on the left side and collect numeric values on the right side.
subtract 18 from both sides.
#3xcancel(+18)cancel(-18)=-3-18#
#rArr3x=-21# To solve for x, divide both sides by 3
#(cancel(3) x)/cancel(3)=(-21)/3#
#rArrx=-7" is the solution"#
