2x + 18

The first step is to remove the brackets.

hence : 12x + 20 -10x - 2

now collect 'like terms'

#color(red)(12x-10x)+color(blue)(20-2)=2x+18#

#2x +18#

Remove the brackets first. Remember that the negative sign will change the signs in the second bracket.

#12x+20-10x-2 " collect like terms"#

#2x +18#
