2


<u>Explanation</u>

The two angles in the diagram are directly opposite. Directly opposite angle are equal.

∴ 12x - 7 = 4x + 9

put the like terms together,

12x - 4x = 9 + 7

8x = 16

x = 16/8

  = 2

First set up the equation 12x-7=4x+9

Get all the x's on one side and number on one side so you have 8x= 16

You get X=2
