Answer:
45 becasue it has to be over 43
Step-by-step explanation:
Answer:
The second expression is not equivalent to the initial expression.
Step-by-step explanation:
Given:
.
Clubbing the co-efficient of g and constant terms. we get:
![$ \frac{1}{10}g + (-1)g + 1\frac{3}{10}g + -\frac{1}{10} + - \frac{1}{10} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B1%7D%7B10%7Dg%20%2B%20%28-1%29g%20%2B%201%5Cfrac%7B3%7D%7B10%7Dg%20%2B%20-%5Cfrac%7B1%7D%7B10%7D%20%2B%20-%20%5Cfrac%7B1%7D%7B10%7D%20%24)
This is the first step and is equivalent to the initial expression.
Now, Simplifying the above expression we have:
![$ \frac{1}{5}g - g + \frac{13}{10}g + (- \frac{2}{10} )$](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B1%7D%7B5%7Dg%20-%20g%20%2B%20%5Cfrac%7B13%7D%7B10%7Dg%20%2B%20%28-%20%5Cfrac%7B2%7D%7B10%7D%20%29%24)
⇒ ![$ ( \frac{1}{5} - 1 + \frac{13}{10}) g $](https://tex.z-dn.net/?f=%24%20%28%20%5Cfrac%7B1%7D%7B5%7D%20-%201%20%2B%20%5Cfrac%7B13%7D%7B10%7D%29%20g%20%24)
⇒ ![$ g (\frac{2 -10 + 13}{10}) - \frac{2}{10} $](https://tex.z-dn.net/?f=%24%20g%20%28%5Cfrac%7B2%20-10%20%2B%2013%7D%7B10%7D%29%20-%20%5Cfrac%7B2%7D%7B10%7D%20%24)
⇒![$ \frac{5}{10}g - \frac{2}{10} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B5%7D%7B10%7Dg%20-%20%5Cfrac%7B2%7D%7B10%7D%20%24)
⇒ ![$ \frac{1}{2}g - \frac{1}{5} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B1%7D%7B2%7Dg%20-%20%5Cfrac%7B1%7D%7B5%7D%20%24)
This is not the second step done by him. Not equivalent to the initial step.
