Question

determinati nerele naturale care verifica egalitatile:
h)7·(15·x+35·x):10+2·x=186

Answer 1

7x50x:10+2X=186
350X:10+2X=186
35X+2X=186
37X=186
X=calculeaza tu

Answer 2

h)7·(15·x+35·x):10+2·x=186
7×50x:10+2x=186
350x:10+2x=186
35x+2x=186
37x=186=>x=186/37

7×(15×186/37+35×186/37):10+2×186/37=?
7×(2790/37+6510/37):10+372/37=?
7×9300/37:10+372/37=?
65100/37:10+372/37=?
65100/37×1/10+372/37=?
65100/370+ 372/37 (65100/370 se simplifica cu 10=6510/37)
6510/37+372/37=?
6882/37=186
