Tìm x, biết a, x ×6+167=191 b,x ÷8 ÷6=12 c, 682+x ÷5=718 d,x ÷8-16=37 các bạn giúp mình vs

a, $x^{}$ x $6^{}$ + $167^{}$ = $191^{}$

$x^{}$ x $6^{}$ = $191^{}$ – $167^{}$

$x^{}$ x $6^{}$ = $24^{}$

$x^{}$ = $24^{}$ : $6^{}$

$x^{}$ = $4^{}$ 

b, $x^{}$ : $8^{}$ : $6^{}$ = $12^{}$

$x^{}$ : $8^{}$ = $12^{}$ x $6^{}$

$x^{}$ : $8^{}$ = $72^{}$

$x^{}$ = $72^{}$ x $8^{}$

$x^{}$ = $576^{}$ 

c, $682^{}$ + $x^{}$ : $5^{}$ = $718^{}$

$x^{}$ : $5^{}$ = $718^{}$ – $682^{}$

$x^{}$ : $5^{}$ = $36^{}$

$x^{}$ = $36^{}$ x $5^{}$

$x^{}$ = $180^{}$

d, $x^{}$ : $8^{}$ – $16^{}$ = $37^{}$

$x^{}$ : $8^{}$ = $37^{}$ + $16^{}$

$x^{}$ : $8^{}$ = $53^{}$

$x^{}$ = $53^{}$ x $8^{}$

$x^{}$ = $424^{}$
