First Brand, L%
Second Brand, H%
Desired Target concentration, T%
Mixture Volume, M
v, the unknown volume of the H% brand
M-v, unknown volume of the L% brand

L%28M-v%29%2BHv=TM
-
LM-Lv%2BHv=TM
Hv-Lv=TM-LM
v%28H-L%29=M%28T-L%29
highlight%28v=M%28%28T-L%29%2F%28H-L%29%29%29
Substitute your given values.

L=9
H=14
T=11
M=350

Evaluate M-v.
