Question

rezolvati va rog dau coroana : {[4+8 ori (10-3 ori x)] :6-1} ori 7=35

Answer 1

Rezolvam prin metoda mersului inapoi
{[4+8*(10-3*x)]:6-1}*7=35
[4+8*(10-3*x)]:6-1=35*7
[4+8*(10-3*x)]:6-1=245
[4+8*(10-3*x)]:6=245+1
[4+8*(10-3*x)]:6=246
[4+8*(10-3*x)]=246*6
4+8*(10-3*x)=1476
8*(10-3*x)=1476-4
8*(10-3*x)=1472
10-3*x=1472:8
10-3*x=184
-3*x=184-10
-3*x=174
x=174:(-3)
x=-58
