Question

Реши урвнение
120+x*3=375
24000:(x-12)=80
x:26+1654=2610

Answer 1

1).
$120+3x=375 \\ 3x=375-120 \\ 3x=255 \\ x=85$
2).
$24000:(x-12)=80 \\ 24000=80(x-12) \\ 24000=80x-960 \\ 24000-960=80x \\ 80x=23040 \\ x=23040:80 \\ x=288$
3).
$x:26+1654=2610 \\ x:26=2610-1654 \\ x:26=956 \\ x=956*26 \\ x=24856$
