First multiply 2/3*9x=6x
then multiply 2/3*-6=-4
this being 6x-4.
then multiply 4*x=4x
then multiply 4*2=8
this being 4x+8.
so we have 6x-4=4x+8+2
we add the 8+2=10
6x-4=4x+10
now we subtract the x to both sides (choose 4x)
2x-4=10
now we add 4 to both sides.
2x=14
we divide 2 to both sides.
we get x=7
final answer:x=7
Answer:
The problem in the first statement is that it does not say that the lines must be in the same plane.
Suppose in a 3D coordinate axis two lines as:
z = 0, y = 0 (this is the x-axis)
y = 1, x = 0 (this line is parallel to the z-axis but one unit above).
Those two lines are not parallel, and also never meet, so the definition is wrong.
The actual definition should be:
"Parallel lines are two lines that lie on the same plane and never meet"
B: The undefined terms are point, line, plane,...
An example can be "Plane", because if our lines do not lie on the same plane, then we can not use the concept of "parallel lines".
Answer:
1st blank=
2nd blank=
3rd blank= 
3*27=81
so 1*=81
hence =81
9* = 81
=9
27*=81
=3
Thus solved.
