Show that 7x + 1 is equivalence to 2(2x - 1) + 3(x + 1)
2 answers:
7x + 1 = 2(2x - 1) + 3(x + 1)
7x + 1 = 4x - 2 + 3x + 3

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 )
