I worked them out separately if I'm correct, then the order is:

x+5y=-2
x+5y=4  These are Inconsistent

y=3x+4
-2x+y=4   These are Consistent independent

3x+y=4
-6x-2y=-8 These are coincident

Inconsistent lines=No solution
Coincident lines=exactly on top of each other
Consistent Independant= Solution, as they cross each other. 

~Hope this helps!

X/9 times 15-47=28<br> help pls
DIA [1.3K]

Answer:

x=45

Step-by-step explanation:

Then,

x/5(15)-47=28

Step 1: Simplify the equation on both sides

x/9(15)-47=28

5/3x-47=28

Step 2: Add 47 to both sides

5/3x-47+47=28+47

5/3x=75

Step 3: Multiply both sides by 3/5

(3/5)*(5/3x)=(3/5)*(75)

x=45
