Question

Is 4x + 9 equivalent to 2(2x+5) -1?

Answer 1

Yes

Explanation:

Set them equal to each other to see. If they are, then you should come out with the answer 0 = 0.

4x + 9 = 2(2x + 5) - 1

4x + 9 = 4x + 10 - 1

0 = 0

Answer 2

Answer: Yes!

Explanation:

1. So you have: 4x+9 and 2(2x+5)-1

2. Simplify the 2nd expression: 2(2x+5) -1 = 4x + 10 - 1 = 4x+9

4x+9 = 4x+9
