Question

cine poate rezolva ecuatia:420-(458-1000:X)+24(INMULTIT)CU7=180

Answer 1

420-(458-1000:x)+24*7=180
427+168-(458-1000:x)=180
595-(458-1000:x)=180
458-1000:x=595-180
459-1000:x=415
1000:x=459-415
1000:x=44
x=1000:44
x=22,(72)

Answer 2

420-(458-1000÷X)+;24×7=180
420-(458-1000÷X)+168=180
420 - ( 458-1000 ÷ X ) =180-168
420 - ( 458-1000 ÷ X ) =12
458-1000 ÷ X =420-12
458-1000 ÷ X =408
100÷x=458-408
1000 ÷x=50
X=1000 ÷50
X=20
