2x+5=4x-7 that's the equation.

The number is 6, I believe. The way to do that is...

You have to put 2x on the other side

then add 7 to both sides

then divide both sides by 2

here is the worked out thing ↓↓↓

2x+5=4x-7

-2x     -2x

---------------

5=2x-7

+7    +7

------------

12=2x

/2  /2

--------

6=x
