Question

[(563x12+Ax3-5):4+328:8]x24-136x13=39848(plz)

Answer 1

[(6756+3A-5):4+41]x24-1768=39848
[(6756 +3A -5) :4 +41 ] x24 =39848 +1768
[( 6756 + 3A -5 ) :4 +41 ] =41616 :24
(6756 +3A -5) :4= 1734
(6756 + 3A -5 ) :4 =1693 ×4
6756 +3A = 6772 +5
3A =6772 -6756
3A = 21
A = 21 : 3
A = 7

Answer 2

[(6756+ax3-5):4+41]x24-1768=39 848
(6 756+ax3-5):4+41=(39 848+1 768):24
(6 756+ax3-5):4+41=1 734
6 756 +ax3-5=(1 734-41)x4
6 756+ax3-5=6 772
ax3=6 772+5-6 756
ax3=21
a=21:3
a=7
