Răspuns :

(a×8+450×250)÷3 147+[(83×6×8 - (20 000-16 216)]=300

(a×8+112 500)÷3 147+[(498×8) - 3 784]=300

(a×8+112 500)÷3 147+(3 984 - 3 784)=300

(a×8+112 500)÷3 147+200=300

(a×8+112 500)÷3 147 = 300 - 200

(a×8+112 500)÷3 147 = 100

a×8+112 500 = 100 × 3 147

a×8+112 500 = 314 700

a×8 = 314 700 - 112 500

a×8 = 202 200

a = 202 200 : 8

a = 25 275
