\([(a+3)*8+26]:5=18 \\\\ (a+3)*8+26=18*5 \\\\ (a+3)*8+26=90 \\\\ (a+3)*8=90-26 \\\\ (a+3)*8= 64 \\\\ a+3=64:8 \\\\ a+3=8 \\\\ a=8-3 \\\\ \boxed{a=5}\)
so [(a+3)8+26]/5=18multiply out[8a+24+26]/5=18add(8a+50)/5=18bultiply both sides by 58a+50=90subtract 50 from both sides8a=40divide both sides by 8a=5
