3x%2B5x%2B9x%2B12x=319 Start with the given equation.


29x=319 Combine like terms on the left side.


x=%28319%29%2F%2829%29 Divide both sides by 29 to isolate x.


x=11 Reduce.


Now plug x = 11 into 6x+%2B+3


6x+%2B+3+=+6%2A11%2B3


6x+%2B+3+=+69


----------------------------------------------------------------------

Answer:

So, 6x+%2B+3+=+69
