Answer:
[tex]\boxed{x = 4}[/tex]
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
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
