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
[(mx12-324):6+11]x7-150 = 25
[(mx12-324):6+11]x7 = 25+150 = 175
(mx12-324):6+11 = 175:7 = 25
(mx12-324):6 = 25-11 = 14
mx12-324 = 14x6 = 84
mx12 = 84+324 = 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 = 25 +150 
[ ( 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
