Question

Aflati valoarea necunoscutei :
[(m×12-324):6+11]×7-50×3=25
Va rog ajutati ma !!!!!!!!!!!!!!

Answer 1

[ ( m × 12 - 324 ) : 6 + 11 ] × 7 - 50 × 3 = 25
[ ( m × 12 - 324 ) : 6 + 11 ] × 7 - 150 = 25
[ ( m × 12 - 324 ) : 6 + 11 ] × 7 = 150 + 25
[ ( m × 12 - 324 ) : 6 + 11 ] × 7 = 175
[ ( m × 12 - 324 ) : 6 + 11 ] = 175 : 7
( m × 12 - 324 ) : 6 + 11 = 25
( m × 12 - 324 ) : 6 = 25 - 11
( m × 12 - 324 ) : 6 = 14
( m × 12 - 324 ) = 14 × 6
m × 12 - 324 = 84
m × 12 = 324 + 84
m × 12 = 408
m = 408 : 12
m = 34

Answer 2

[ ( m × 12 - 324 ) : 6 + 11 ] × 7 - 50 × 3 = 25
[ ( m × 12 - 324 ) : 6 + 11 ] × 7 - 150 = 25
[ ( m × 12 - 324 ) : 6 + 11 ] × 7 = 150 + 25
[ ( m × 12 - 324 ) : 6 + 11 ] × 7 = 175
 ( m × 12 - 324 ) : 6 + 11 = 175 : 7 
( m × 12 - 324 ) : 6 + 11 = 25
( m × 12 - 324 ) : 6 = 25 - 11
( m × 12 - 324 ) : 6 = 14
 m × 12 - 324  = 14 × 6 
m × 12 - 324 = 84 
m × 12 = 84 + 324
m × 12 = 408
m = 408 : 12 
m = 34

Verific:
[(34 × 12 - 324 ) : 6 +11] × 7 - 150 = 25
= [(408 - 324 ) : 6 + 11]×7 - 150 =
= ( 84 : 6 +11 ) × 7 - 150=
=  (14 + 11) × 7-150=
= 25 x 7 -150=
= 175 - 150 =
= 25
