Answer:
x =5/ (1-a)
Step-by-step explanation:
3x-ax=2x+5
Subtract 2x from each side
3x -ax-2x = 2x+5-2x
3x -ax -2x = 5
combine like terms
x-ax = 5
Factor out x
x(1-a) =5
Divide each side by 1-a
x =5/ (1-a)
X - the percent of increase
![210+210x=260 \\ 210x=260-210 \\ 210x=50 \\ x=\frac{50}{210} \\ x \approx 0.238 \\ x \approx 23.8\%](https://tex.z-dn.net/?f=210%2B210x%3D260%20%5C%5C%0A210x%3D260-210%20%5C%5C%0A210x%3D50%20%5C%5C%0Ax%3D%5Cfrac%7B50%7D%7B210%7D%20%5C%5C%0Ax%20%5Capprox%200.238%20%5C%5C%0Ax%20%5Capprox%2023.8%5C%25)
The percent of increase is approximately 23.8%.
