Question

Determina valoarea necunoscutelor din egalitatile.
(242+360:10-214):(80:5-4×2)•a= 240

Answer 1

(242+360:10-214):(80:5-4*2)*a=240
(242+36-214):(16-8)*a=240
(278-214):8*a=240
64:8*a=240
8*a=240
a=240:8
a=30

Answer 2

(242+360:10-214):(80:5-4×2)•a= 240
( 242 + 36 - 214) : ( 16 - 8) × a =240
( 278 - 214 ) : 8 ×a = 240
64 : 8 × a = 240
8 × a = 240
 a = 240 : 8
a = 30
