(((a+8)×5)÷10)-3=2
((a+8)×5)÷10=2+3=5
(a+8)×5=5×10=50
a+8=50÷5=10
a=10-8=2
sper sa te ajute!

[( a + 8 ) x 5 ] : 10 -3 = 2
[ ( a +8 ) x 5 ] : 10 = 2 + 3
[ ( a +8 ) x 5 ] : 10 = 5
( a + 8 ) x 5 = 5 x 10
( a + 8 ) x 5 = 50
a +8 = 50 : 5
a + 8 = 10
a = 10 - 8
a = 2
[ ( a +8 ) x 5 ] : 10 = 2 + 3
[ ( a +8 ) x 5 ] : 10 = 5
( a + 8 ) x 5 = 5 x 10
( a + 8 ) x 5 = 50
a +8 = 50 : 5
a + 8 = 10
a = 10 - 8
a = 2
