Find x if 3x-(x-4) = 3x+1 ?​

3

Step-by-step explanation:

3x - ( x - 4 ) = 3x + 1

3x - x + 4 = 3x + 1

2x + 4 = 3x + 1

3x - 2x = 4 - 1

x = 3

Hope it will help :)

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
