Solve, show your work. Solve 5x + 4 = 14x - 14

 x = 2

Step-by-step explanation:

Pull out like factors :

  -9x + 18  =   -9 • (x - 2)

Solve :    -9   =  0

Solve  :    x-2 = 0  

Add  2  to both sides of the equation :  

                     x = 2

I HOPE THIS HELPS YOU! :)

step-by-step explanation:

8+8+6+6

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
