Question

Sa se determine x din egalitate 13•(462-x•152:8)-866=200

Answer 1

13 × ( 462 - x × 152 : 8 ) - 866 = 200

13 × ( 462 - x × 19 ) - 866 = 200

13 × ( 462 - x × 19 ) = 200 + 866

13 × ( 462 - x × 19 ) = 1066

462 - x × 19 = 1066 : 13

462 - x × 19 = 82

x × 19 = 462 - 82

x × 19 = 380

x = 380 : 19

x = 20

Answer 2

Explicație pas cu pas:

13•(462-x•152:8)-866=200

13•(462-ו152:8)=866+200=1066

462-ו19=1066:13

462-ו19=82

ו19=462-82

ו19=380

×=380:19

×=20
