Answer:
The value of x is -4/5.
Step-by-step explanation:
First, you have to get rid of brackets, by expanding out :
2(6x+10) - 3x = 10 - (x-2)
2(6x) + 2(10) - 3x = 10 - x + 2
12x + 20 - 3x = 10 - x + 2
Next, is to bring all the x variable to one side :
12x + 20 - 3x = 10 - x + 2
12x - 3x + x = 10 + 2 - 20
10x = -8
Lastly, is to solve it by dividing 10 to both sides :
10x = -8
10x ÷ 10 = -8 ÷ 10
x = -4/5

Step-by-step explanation:
Hey There!
So remember in order for it to be a proportional relationship it has to be a straight line and it has to go through the origin (0,0)
The 2nd, 4th and 5th ones are non proportional relationships
Why? Well because they don't go through the origin
they are the same. they are = (equal)
