Answer 1

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 2

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
