Answer:
Explanation:
First, you need to set your expressions equal to each other.
h(x) = 8
h(x) = 3x-2/5
8 = 3x-2/5
Now, you need to add 2/5 to both sides. To balance the equation and isolate 'x'
8 = 3x-2/5
8+2/5 = 3x
Then, divide both sides by 3. Once you do this 'x' should be isolated.
8+2/5 = 3x
(8+2/5) / 3 = x
The final step is to simplify your answer. Personally, I just leave it as an improper fraction, but I put the decimal value as well.
(8+2/5) / 3 = x
(40/5 +2/5) / 3 = x
(42/5) / 3 = x
(42/5) * (1/3) = x
42/15 = x
14/5 = x
2.8 = x
