x=9

Explanation:

Substitute the y value:

2x+(3⋅6)=36

2x+18=36

Subtract 18 from both sides to isolate the 2x:

2x=36−18

2x=18

Divide both sides by 2 to get x on its own:

x=182

x=9

Thus, we have our answer.

Our function is:

f(x)=12^3+ax-20

Now, if 3x+4 is a factor of f(x) then $x=\frac{-4}{3}$ must satisfy the equation:

So, $f(\frac{-4}{3} )=0$

Putting $x=\frac{-4}{3}$

We get,

$f(\frac{-4}{3} )=12^3+a(\frac{-4}{3} )-20=0$

$12^3+\frac{-4}{3} a-20=0$

$\frac{-4}{3} a=20-12^3=20-1708$

$a=-1708 \times \frac{-3}{4} =1281$

So, the value of 'a' for the given expression is 1281.
