Answer:

x = 4

Step-by-step explanation:

5x - 4 + 2(x-4) = 16

Expand the equation by multiplying 2 to x and -4 separately:

5x - 4 + 2x - 8 = 16

Collect like terms:

5x + 2x - 4 - 8 = 16

7x -12 = 16

Add 12 to both sides:

7x = 16 + 12

7x = 28

Divide both sides by 7 :

x = 28/7

x = 4

Answer:

$\boxed{x = 4}$

Step-by-step explanation:

=> 5x-4+2(x-4) = 16

Expanding the brackets

=> 5x-4+2x-8 = 16

Combining like terms

=> 5x+2x-4-8 = 16

=> 7x - 12 = 16

Adding 12 to both sides

=> 7x = 16+12

=> 7x = 28

Dividing both sides by 7

=> x = 4

The sketch answers to question 8, 9 and 10 is given in the image attached.

<h3>What is an intersecting lines?</h3>

A link is known to be intersecting if two or more lines are said to have cross one another in a given plane.

Note that the intersecting lines are known to be one that often share a common point, and it is one that can be seen on all the intersecting lines, and it is known to be the point of intersection.

Looking at the image attached, you can see how plane A and line c intersecting at all points on line c and also GM and GH and line CD and plane X as they are not intersecting

Therefore, The sketch answers to question 8, 9 and 10 is given in the image attached.
