Look at the picture.
The equation:
10x - 15 = 6x + 9 <em>add 15 to both sides</em>
10x = 6x + 24 <em>subtract 6x from both sides</em>
4x = 24 <em>divide both sides by 4</em>
<h3>
x = 6</h3>
Answer:
Not necessarily words, because there is nothing hard to define in geometry, something hard to LEARN is theorems and postulates though.
Step-by-step explanation:
Hope this helps! :)
X=6,-6
3x= 18
X=18/3
X= 6,-6
