3x+4y+6z=15<br>Solve for x.​
aalyn [17]

Answer:

<h2> </h2><h2>x = 5 -  \frac{4}{3} y - 2z</h2>

Step-by-step explanation:

<h3><u>Question</u><u>:</u><u>-</u></h3>
  • To solve for x

<h3><u>Equation</u><u>:</u><u>-</u></h3>
  • 3x + 4y + 6z = 15

<h3><u>Solution</u><u>:</u><u>-</u></h3>

=> 3x + 4y + 6z = 15

  • <em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>4y</em><em>]</em>

=> 3x + 4y + 6z - 4y = 15 - 4y

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 3x + 6z = 15 - 4y

  • <em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>6z</em><em>]</em>

=> 3x + 6z - 6z = 15 - 4y - 6z

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 3x = 15 - 4y - 6z

  • <em>[</em><em>On</em><em> </em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>3</em><em>]</em>

=  >  \frac{3x}{3}  =  \frac{15 - 4y - 6z}{3}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  > x = 5 -  \frac{4}{3} y - 2z \: (ans)
