Hello If You Have Please Help Thank You<br> Solve for x.<br><br> −7x−15&lt;6
bonufazy [111]

Answer:

x > -22/7

Step-by-step explanation:

Given inequality:

- 7x - 15 < 6

<em>adding 15 to both sides:</em>

==> -7x - 15 + 15 < 6 + 16

==> -7x < 22

<em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>7</em><em>:</em>

==> -x < 22/ 7

<em>multiplying</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em>1</em>

<em>(</em><em>anytime</em><em> </em><em>you</em><em> </em><em>multiply</em><em> </em><em>the</em><em> </em><em>inequality</em><em> </em><em>by</em><em> </em><em>-</em><em>1</em><em> </em><em>you</em><em> </em><em>must</em><em> </em><em>flip</em><em> </em><em>th</em><em>e inequality sign–</em><em> </em><em>r</em><em>e</em><em>p</em><em>l</em><em>a</em><em>c</em><em>e</em><em> </em><em>the</em><em> </em><em>"</em><em><</em><em>"</em><em> </em><em>with</em><em> </em><em>"</em><em>></em><em>"</em><em>)</em>

==> <u>x > -22/7</u>
