Fully answer the question below

Answer 1

The second expression is not equivalent to the initial expression.

Explanation:

Given:
`$ (1)/(5)g - (1)/(10) -g + 1(3)/(10)g - (1)/(10) $`.

Clubbing the co-efficient of g and constant terms. we get:

`$ (1)/(10)g + (-1)g + 1(3)/(10)g + -(1)/(10) + - (1)/(10) $`

This is the first step and is equivalent to the initial expression.

Now, Simplifying the above expression we have:

`$ (1)/(5)g - g + (13)/(10)g + (- (2)/(10) )$`

⇒
`$ ( (1)/(5) - 1 + (13)/(10)) g $`

⇒
`$ g ((2 -10 + 13)/(10)) - (2)/(10) $`

⇒
`$ (5)/(10)g - (2)/(10) $`

⇒
`$ (1)/(2)g - (1)/(5) $`

This is not the second step done by him. Not equivalent to the initial step.
