Question

Aflati X din: 700[400–(x–300)]=850


VA ROG AJUTATIMA DAU COROANA SI PUNCTAJ MAXIM E URGENT!!!!!!

Answer 1

700×[400-x-300)]=850

Aplicam metoda mersului invers:

850 = [(300 + X) +400] ×700

[(300+X)+400] =850×700

[(300+ X)]+400] = 595000

x+400=595000+300

X+400=595300

X=595300-400

X=59460

Succes!
