The Cartesian equation must pass through the point $(3,-1,2)$ and must be perpendicular to the LOI of the planes $3x-2y+1=0$ and $3x+4z-5=0$ Vectors was never really my strong suit, if anyone could help me that would be great.

The vectors normal to your planes are $(3,-2,0)$ and $(3,0,4)$ Find their cross product $$ (3,-2,0) \times (3,0,4) = (8,-12,6)$$ which is a vector parallel to the LOI . Using the given point the LOI is $$(x,y,z)= (3,-1,2)+t(8,-12,6)$$
