Va rogggggggggg

Answer 1

Răspuns:

Explicație pas cu pas:

1578-789x{5-3x[(X - 48):4-15]}=0

789 -{5 - 3 x [( X - 48 ) : 4 - 15]}= 1578-0

789 - {5 - 3 x [( X - 48) : 4 - 15]}= 1578

5 - 3 x [(X - 48 ) : 4 - 15 ] = 1578 : 789

5 - 3 x [(X - 48 ) : 4 - 15 ] = 2

3 x [( X- 48 ) : 4 - 15 ] = 5 - 2

3 x [(X - 48 ) : 4 - 15 ] = 3

( X - 48 ) : 4 - 15 = 3 : 3

( X - 48 ) : 4 - 15 = 1

( X - 48 ) : 4 = 1 + 15

( X - 48 ) : 4 = 16

X - 48 = 16 x 4

X - 48 = 64

X = 64 + 48

X = 112
