Question

2 şi 3
Vă rogggg!!!!!
Mulțumesc mult!!!!

Answer 1

2)56+ {15+ 2 x [(35-30)x 6+26]-105} x 2
56+[15 + 2 x (30+26)-105] x2
56 + [15 +2 x 56-105) x 2
56+ 15+102-105 x 2
56+12 x2
56+24
=80
3)96:(a-6)=3 =) a-6=32 ->a=38
(a+2) x 5= 555 =>a+2=111 ->a=109
a+265-384=2010 =>a -119=2010 =>a=2129
368:(25+a)=8
=>25+a =46=>a=21

Answer 2

2) 56+{45÷3+2*[(105÷3-240÷8)*6+26]-105}*2=56+{15+2*[(35-30)*6+26]-105}*2=56+{15+2*5*6+26]-105}*2=56+{15+60+26-105}*2=56+{111-105}*2=56+6*2=56+12=68
3)96÷(a-6)=3
96÷a=3+6
96÷a=9
a=9*96
a=864

(a+2)×5=555
a+2=555÷5
a+2=111
a=111-2
a=109

a+265-384=2010
a=2010-265+384
a=1754+384
a=2129

368÷(25+a)=8
368+a=8*25
368+a=200
a=368-200
a=168.
