Explanation:
#"distribute parenthesis on the right side of the equation"#
#20=14+3x+24#
#rArr20=38+3x#
#"subtract 38 from both sides"#
#20-38=cancel(38)cancel(-38)+3x#
#rArr-18=3x#
#"divide both sides by 3"#
#(-18)/3=(cancel(3) x)/cancel(3)#
#rArrx=-6#
#color(blue)"As a check"# Substitute this value into the right side of the equation and if equal to the left side then it is the solution.
#14+3(2)=14+6=20="left side"#
#rArrx=-6" is the solution"#
