$53x+53$

Notice that there are 2 terms.
Start my removing the brackets within each term using the distributive law

$color(red)(2[3(3x +1)+ 2( 2x +5)] )+ color(blue)(3([1+ 4(x+2)+5x]$

= $color(red)(2[9x +3+ 4x +10)] + color(blue)(3[1+ 4x+8+5x]" "larr$ simplify

= $color(red)(2[13x +13)] + color(blue)(3[9x+9])" "larr$ remove brackets

= $26x+26 +27x+27" "larr$ simplify

= $53x +53$
