Question 1196466
<pre>

{{{(9v/10) + (.0013*v/ 10) = xv}}}

Clear fractions by multiplying every term on both sides by {{{10/v}}}

{{{expr(10/v)(9v/10) + expr(10/v)(.0013*v/ 10) =expr(10/v)xv}}}

Cancel 10's and v's on the left and the v's on the right

{{{expr(cross(10)/cross(v))(9cross(v)/cross(10)) + expr(cross(10)/cross(v))(.0013cross(v)/cross(10)) =expr(10/cross(v))x*cross(v)}}}


{{{9+.0013=10x}}}

Add the numbers on the left

{{{9.0013=10x}}}

Divide both sides by 10

{{{9.0013/10=10x/10}}}

Divide on the left, cancel the 10's on the right:

{{{0.90013 =cross(10)x/cross(10)}}}

{{{0.90013=x}}}
