Answer:
x=14
Step-by-step explanation:
2(3x-4)=5x+6
first get rid of the parentheses by multiplying the 2
6x-8 = 5x+6
put like terms on one side of the equation. Start with the 5x, move it to the left side
(6x-8)-5x = (5x+6)-5x
x-8 = 6
Again, put like terms on one side of the equation. Move the 8 to the right side
(x-8)+8 = 6+8
=> x = 14
B)
4x - 3 = 2(x-1)
Start again by getting rid of the parentheses to make it a clean equation... aka distribute the 2:
4x-3 = 2x - 2
Move the like terms to one side of the equation. Start with x.. move 2x to the left:
(4x-3)-2x = (2x-2)-2x
=> 2x-3 = -2
Move the like terms to one side of the equation.Now move the -3 to the other side:
(2x-3)+3 = -2+3
=> 2x=1
Lastly, divide by 2 on both sides to find out what x is:
(2x)/2=1/2
=> x = 1/2
..so no, Charlie was incorrect.
You can notice the sequence:
5*2=10
3*3=9
following the same sequence:
2*6=12
therefore, the missing number is 12
(2,6,12)

Answer:
(q,0)
Step-by-step explanation:
See the diagram given.
It is clear from the coordinates of the points given that point C (0,r) lies on the Y-axis and point E (-q,o) lies on the X-axis. Hence, point D must be on the X-axis.
ΔCDE being an isosceles triangle, the origin of the coordinate axes will be on the DE line and it will be at the midpoint of DE.
Therefore, ΔCDE will be symmetric with respect to the Y-axis and the coordinates of point D will be (q,0). (Answer)
