Which shows the correct solution of the equation, when b= 30?

Step-by-step explanation:

You have the following equation:

 In order to find the solution of the given equation when , you need to substitute this value of "b" into the equation and then you must solve for  "a".

Applying this procedure, you get that the solution of the equation when   is:

{a:a=60}

Step-by-step explanation:

The given equation is

We first multiply through by the Least Common Multiple of 2 and 3, and simplify.

We then make a the subject,so we subtract 4b from both sides of the equation to get

We then divide through by 3

We substitute b=30 into the simplified equation to get

Hence the correct solution of the equation is {a:a=60}

answer4 to the second power is 16

and 4 to the third power is 64,
