7x + 1 = 2(2x - 1) + 3(x + 1)

7x + 1 = 4x - 2 + 3x + 3

7x + 1 = 7x + 1

Answer with Step-by-step explanation:

2 ( 2x -1 ) + 3 ( x + 1 )

First, let us <u>find the value of the above expression.</u>

2 ( 2x -1 ) + 3 ( x + 1 )

4x - 2 + 3x + 3

<em>Combine like terms</em>

4x + 3x - 2 + 3

<u>7x + 1</u>

Therefore, it is clear that the given expression is equal to 7x + 1.

∴ 7x + 1 = 2 ( 2x -1 ) + 3 ( x + 1 )
