Решите пожалуйста уравнения! 419- x:6=349

419- x:6=349

x:6=419-349

x:6=70

x=70*6

x=420

419-420:6=349

<span>419- x:6=349</span>

<span>х : 6 = 419 - 349</span>

<span>х : 6 = 70</span>

<span>х = 70 * 6</span>

<span>х = 420</span>

<span>______________</span>

<span>419 - 420 : 6 = 349</span>
