Question

PLEASE SOMEONE ANSWER I'VE ASK THIS QUESTION 3 TIMES AND NO ONE ANSWERS ME.

A. Write an expression based on the given statement

b. Simplify the expression you just wrote
------
1. Find the sum of -7g and 4g + 2

2. Find the difference when 6ん is subtracted from 2ん - 4

Answer 1

1 a)
`-7g+4g+2`

1 b)
`-3g+2`

2 a)
`2\lambda-4-6\lambda`

2 b)
`-4\lambda-4`

Explanation:

Given statements:

1. Find the sum of -7g and 4g + 2

2. Find the difference when 6
`\lambda` is subtracted from 2
`\lambda` - 4

a) To write an expression based on the given statement

b) To simplify the expression

Solution:

1) The expression for sum of
`-7g` and
`4g+2` is given as:

1 a)
`-7g+4g+2`

The above expression can be simplified by combining the like terms:

1 b) ⇒
`-3g+2` [ As
`-7g+4g=-3g` ]

2) The expression for the difference when
`6\lambda` is subtracted from
`2\lambda-4` can be given as:

2 a)
`2\lambda-4-6\lambda`

The above expression can be simplified by combining the like terms:

2 b) ⇒
`-4\lambda-4` [ As
`2\lambda-6\lambda = -4\lambda` ]
