Hi,
Now that I am understanding Your question properly:
Mixing 2m^3 of 35% solution with 6m^3 of 15% solution
Generally, recommend letting x represent a 'decimal value' on the right side
         Mixing
 .35*2m^3 + .15*6m^3 = x* 8m^3  
      1.6m^3 = x*8m^3
      1.6/8 = x
        .20 = x    |.20 = 20/100 OR 20%    |Converting the decimal to Percent
     mixing will result in 8m^3 of  20% Solution

If I am understanding Your Question properly: disregard
{{{.35*2m^3 + .15*6m^3 =  x/(100*8m^3)}}}
{{{.70m^3 + .90m^3 = x/(100*8m^3)}}}
{{{1.6m^3 = x/(100*8m^3)}}}
{{{1.6m^3 * (100*8m^3) = x}}}    
{{{1.6m^3 * (800m^3) = x}}}    |{{{( x^m )( x^n ) = x^( m + n )}}}
      x = 1280m^6
