The answer should be X>4

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :  

                    2*x+8-(5*x-4)<0  

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -3x + 12  =   -3 • (x - 4)  

Equation at the end of step  1  :

Step  2  :

2.1    Divide both sides by  -3  

Remember to flip the inequality sign:  

Solve Basic Inequality :

2.2      Add  4  to both sides

            x > 4

What’s the answer??????? Pleaseeeeeeee helppppppppppp
Vinvika [58]

Hello from MrBillDoesMath!

Answer:

Choice A,   18x - 6y = 20


Discussion:

Given line  

-9x + 3y = 12     (M)


Choice A:

18x - 6y = 20  =>          divide both sides by -2

-9x + 3y = -10     (N)


The left hand sides of (M) and (N) are equal implying that right hand sides are equal which further implies 12 = -10.  Contradiction! so the system M and N has no solution.


Thank you,

MrB
