rezolvati ecuatia 7×2+{4×[7×4+(a+2):6]-5}:5=37. Mersi anticipat

Answer 1

7×2+{4×[7×4+(a+2):6]-5}:5=37
14+{4×[28+(a+2):6]-5}:5=37
{4×[28+(a+2):6]-5}:5=37-14
{4×[28+(a+2):6]-5}:5=23
4×[28+(a+2):6]-5=23×5
4×[28+(a+2):6]-5=115
4×[28+(a+2):6]=115+5
4×[28+(a+2):6]=120
28+(a+2):6=120:4
28+(a+2):6=30
(a+2):6=30-28
(a+2):6=2
a+2=2×6
a+2=12
a=12-2
a=10
