Question

1. Gloria says the two expressions 2(3x+6) - 9x and 3x4 are equivalent,

Is she correct? Explain how you know.

Answer 1

Explanation:

2(3x+6)-9x=3x4

6x+12-9x=3x4

15x+12=3x4

15x+12=12

15x=0

x=0

There is x.

Answer 2

Explanation:

Well, Let's find out!

Gloria says,

2(3x+6)-9x=3*4

By using distributive law

6x+12-9x=12

12-3x=12

-3x=12-12

-3x=0

x=0/-3

So she is not correct
