Just good ole algebraic manipulation
![2a - b = 8b - 4a](https://tex.z-dn.net/?f=2a%20-%20b%20%3D%208b%20-%204a%20)
First, Let's Combine Common Terms
![(2a + 4a) = (8b + 1b) \\ 6a = 9b](https://tex.z-dn.net/?f=%282a%20%2B%204a%29%20%3D%20%288b%20%2B%201b%29%20%5C%5C%206a%20%3D%209b)
Now Let's Divide
![\frac{6a}{6} = \frac{9b}{6} \\ a = \frac{9b}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6a%7D%7B6%7D%20%20%3D%20%20%5Cfrac%7B9b%7D%7B6%7D%20%20%5C%5C%20a%20%3D%20%20%5Cfrac%7B9b%7D%7B6%7D%20)
Let's Simplify That Fraction
![a = \frac{9}{6} \times \frac{b}{1} \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B9%7D%7B6%7D%20%20%5Ctimes%20%20%5Cfrac%7Bb%7D%7B1%7D%20%20%5C%5C)
Answer
Answer: 77/3 or 25 2/3
Step-by-step explanation:
1. Convert mixed numbers into improper fractions:
3 1/2 = 3*2+1/2 = 7/2
2 2/3 = 2*3+2/3 = 8/3
1 1/2 = 1*2+1 = 3/2
2. Calculate within parentheses
Multiply and divide from left to right
Add and subtract from left to right
