  1. $a)225:x=15$

    $ ⇔x=225:15$

    $⇔x=15$

    $\text{Vậy $x=15$}$

    $b)2x+17=33$

    $⇔2x=33-17$

    $⇔2x=16$

    $⇔x=8$

    $\text{Vậy $x=8$}$

    $c)6+10x=6^5:6^3$

    $⇔6+10x=6^{5-3}$

    $⇔6+10x=6^2$

    $⇔6+10x=36$

    $⇔10x=36-6$

    $⇔10x=30$

    $⇔x=3$

    $\text{Vậy $x=3$}$

    Giải thích các bước giải:

     $a)⇔x=225:15$

    $⇔x=15$

    $b)⇔2x=16$

    $⇔x=16:2$

    $⇔x=8$

    $c)⇔6+10x=6^2$

    $⇔10x=36-6$

    $⇔x=30:10$

    $⇔x=3$
