Question

aflati termenul necunoscut...:(45:5+10×2-14)×5×(7×4-14:7):13+92×b=426

Answer 1

(45:5+10×2-14)×5×(7×4-14:7):13+92×b=426
( 9 + 20 - 14 ) x 5 x ( 28 - 2) :13 + 92 x b = 426 
15 x 5 x 26 :13 + 92 x b = 426
1 950 : 13 + 92 x b = 426 
150 + 92 x b = 426
92 x b = 426 - 150
92 x b = 276
b = 276 : 92
b = 3
