If f(x) = 3x +9 x when f(x) = 30
den301095 [7]

Answer:

x=5/2

Step-by-step explanation:

When f(x)=30, we have 3x+9x=30.

Combining like terms on the right side, we have 12x=30.

Finally, dividing by 12 we get x=30/12.

We note that 30=6*5 and 12=6*2, so 30/12=5/2.

So, \boxed{x=5/2} and we're done!
