First multiply the 2 into the parenthesis. Then add the 10 and 2 in order to simplify. Then subtract 4a from both sides. This gives you 12=3a-3. Add 3 on both sides, this gives you 15=3a. Divide 3 on both sides which will give you a =5
The way to solve this is by doing 16/2 which is 8=8 and 4 multiplied by 8 will be 8=8

Answer:
The inverse function is f(x) = (x - 1)/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x + 1
x = 2f(x) + 1
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) + 1
x - 1 = 2f(x)
(x - 1)/2 = f(x)
