Question

X:10*10-x*10:10+x*10:10+x=10*10

Answer 1

Răspuns

Explicație pas cu pas:

x : 10 × 10 - x ×10 : 10 + x × 10 : 10 + x = 10 × 10

x - x + x + x = 100

2 x = 100

x = 100 : 2

x = 50

____________

Verific:

50 : 10 × 10 - 50 × 10 : 10 + 50 × 10 : 10 + 50 = 100

= 50 - 50 + 50 + 50 =

= 0 + 100 =

= 100
