Răspuns :
Daca a×(b+5) = 336
a × b =301
a = ?
avem:
a × b + 5a = 336
a × b = 301
301 + 5a = 336
5a = 336 - 201
5a = 35
a = 35/5
a= 7
a × b =301
a = ?
avem:
a × b + 5a = 336
a × b = 301
301 + 5a = 336
5a = 336 - 201
5a = 35
a = 35/5
a= 7
ax(b+5) = 336 inseamna ca axb + ax5 = 336
Dar axb = 301, atunci
301 + ax5 = 336
ax5 = 336-301
ax5 = 35
a = 35:5
a = 7
Dar axb = 301, atunci
301 + ax5 = 336
ax5 = 336-301
ax5 = 35
a = 35:5
a = 7
