It seems like you want to simplify 7(x-4)

If so, then multiply the outer 7 by each term inside (x and -4)
7 times x = 7x
7 times -4 = -28
Add up the results: 7x+(-28) = 7x-28

Therefore, 7(x-4) turns into 7x-28

7x - 28 = 7x-28 
isolate the variable 
7x-7x= -28+28 
the answer would be zero 
I may be wrong

borishaifa [10]

Answer:

x=10

Step-by-step explanation:

Lets use a ratio.

3:2 (12 to 8)

We need to scale the x+4 up 3/2 to be equal to 2x+1

(3/2) x+4 = 2x+1

1.5x+6=2x+1

-1.5x    -1.5x

6=0.5x+1

-1          -1

0.5x=5

x=10
