Answer:
x = - 15
Step-by-step explanation:
Given
+ 3 = x - 2
Multiply through by 3 to clear the fraction
4x + 9 = 3x - 6 ( subtract 3x from both sides )
x + 9 = - 6 ( subtract 9 from both sides )
x = - 15
Numerical expressions, one half the sum of nine and three

Answer:
POSTULATE
Step-by-step explanation:
<em>A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven </em>
<em> </em>
<em> </em>
<em> </em>
<em>In geometry, the theorem is considered valid or correct with which its assertion is practically not refuted by almost anyone, whether it is really true or not. </em>
<em> </em>
<em> </em>
<em> </em>
<em>This, in practice, implies that all students of the subject share the same criteria on the theory. Thus, the postulates, in short, have the following characteristics: </em>
<em> </em>
<em> They are presumed true by most of the scholars in the field. </em>
<em> </em>
<em>Its contradiction goes against the very essence of the subject. </em>
<em> </em>
<em>Postulate 6: If two planes intersect, then their intersection is a line.</em>

<em>See Attachment for Details ^^</em>
<em>The image attached represents the statement given in the question (If two distinct planes intersect, then their intersection is a line)</em>
<em>Therefore</em><em>, </em>
<em> </em>
<em>The Geometry term that represents the statement above is POSTULATE</em>
