Question

All the statements that are true for any value of x

There are 3 right answers

Hint: Check to see if what is on the left side of the = has the same value and the other side.
Here are the ones to pick from

1. 7x + (2x + 7) = 9x +7
2. 7x +(2x - 1) = 9x + 1
3. 1/2 x + (3 - 1/2) = 3
4. 5x - (8 - 6x) = -x - 8
5. 6x (2x - 4) = 4x + 4

Answer 1

1. 7x + (2x + 7) = 9x +7

2. 7x +(2x - 1) = 9x + 1

3. 1/2 x + (3 - 1/2) = 3

Not sure if this is completely right, but I hope this helps!

Answer 2

Actually there is only one correct answer which is

1. 7x + (2x + 7) = 9x + 7

`7x + (2x + 7) = 9x + 7`

`7x + 2x + 7 = 9x + 7`

`9x + 7 = 9x + 7`

Hope it helps :)
