4.
The equation we have is:
To solve for "a", we want to isolate it in one side.
For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:
Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":
And that is the answer to 4.

Step 1: (\frac{(3)(4)(-1)}{(5)(9)(2)})(
(5)(9)(2)
(3)(4)(−1)
)
Emanuel used negative sign with both numbers 1 and 2. Therefore the first step of Emanuel is incorrect.
Step 2: \frac{-12}{90}
90
−12
Step 3: \frac{-2}{15}
15
−2
Therefore Emanuel made huis mistake in first step and step 1 is incorrect
