6/19=x-12/2x-2
What’s the answer?
the solution for the given equation is x = 30.857.
the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given an equation, 6/19=x-12/2x-2
Simplifying this using PEMDAS
cross multiple the equation
12x -12 = 19x -12*19
on the same side
-7x = -228 +12
-7x = -216
x = 216/7
x = 30.857
Therefore, the solution for the given equation is x = 30.857.

-9x = -9:
x - (-5) = -4:
-5x= 25:
x - (-2) = 10
Answer:
For each of them, you would need to isolate the variable.
Step-by-step explanation:
Okay so for the first one, you would need to isolate the x.
x/-2 = 3
Since the "/" represents division, you need to do the inverse of dividing which is multiplication. You would need to multiply on both sides of the equation.
x = 3 x -2
x = -6
And there you have it, the answer for the first problem!
You again, isolate the x for the second equation as well.
-9x = -9
Since the x is directly next to the 9, indicating that it is multiplication. Do the inverse of multiplication which is division. Divide by -9 on both sides.
x=-9
Since -9/-9 cancels each other out, that leaves x by itself.
x = -9/-9
x = 1
You only end up cancelling out the number next to the variable, not the one on the other side. (if you are wondering why I didn't cross it out)
As for the third one, you can carry the -5 over to the -4, but since the inverse of -5 is +5, you add 5 to -4.
x = 1
As easy as that! You don't do the same as the two questions before because the number isn't right next to the variable.
For the fourth one, you isolate the x once more. You do the inverse of multiplication which is again, division. And again, the -5/-5 cancel out!
x = -5/25
x = -0.2
And finally, the last one!
You repeat the same steps as the third one. Add 2 on each side and cancel out 2 + 2 on the x's side.
x = 10 +2
x = 12
And that's all your answers. Hope you understood :)
Answer:
-733.13
Step-by-step explanation:
Take absolute value of each number
(add absolute value bars to show what you're doing)
-734.8 = 734.8
-1.67 = 1.67
Then do regular subtraction
734.8 - 1.67 = 733.13
Then put back the negative symbol in front and you have your answer
-733.13
