There is some ambiguity in the rendering of your equation, but I'm going to presume you mean:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.35\,\cdot\,2m^3\ +\ 0.15\,\cdot\,6m^3\ =\ \frac{x}{100}\,\cdot\,8m^3]


Further, since you cannot solve this for *[tex \Large m] other than to say *[tex \Large m] is any real number, that you need to solve for *[tex \Large x]


Step 1:  Multiply 0.35 times 2, 0.15 times 6, and *[tex \Large \frac{x}{100] times 8.


Step 2:  Re-write your equation:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.7m^3\ +\ 0.9m^3\ =\ (0.08x)m^3]


Step 3:  Combine like terms in the LHS:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1.6m^3\ =\ (0.08x)m^3]


Step 4:  Multiply both sides by *[tex \Large \frac{1}{m^3}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1.6\ =\ 0.08x]


Solve for *[tex \Large x]

My calculator said it, I believe it, that settles it
