Answer:
12.8
Step-by-step explanation:
4.8 x 2 = 9.6
9.6 + 3.2 =12.8
Say you had this problem:
-4x - 2y= -12
4x +8y = -24
First you would have to cancel out one part of the equation to get on variable alone. In this case it's easy it would be -4x and 4x. So then you would cancel those out.
Now we have
-2y= -12
8y =-24
so then you just add them all up
6y=-36
Next you just divide both sides by 6
so then you answer for y would be -6.
Next you would choose one of your equations and plug the -6 in.
So it would be
-4x -2 (-6) =-24
So you would times negative 2 by negative 6, which would be positive 12. Since a negative times a negative equales a positive.
-4x + 12= -24
Next you would minus 12 on both sides.
-4x + 12=-24
- 12 = -12
The 12's would cancel out and then you just minus -24 by -12 which you would ended up just plusing them together because a negative plus a negative equales a negative. Or a negative minus a negative number would end up adding them up.
-4x= -36
Next you would get x alone and how you would do that is you would divide -4 in both sides which would cancel them -4 out then it would be divided by -36.
So it would look like this.
-4x= -36
-4 -4
So negative 36 divided by negative 4 is 9.
So your final answer would be
y= -6
x= 9
I hope I explained to you properly how to do systems of equations by elimination.

Answer:
Step-by-step explanation:
To find the quotient, we first need to know what quotient means.
Quotient is the solution to division problems.
So here is how we have to do this, first we identify our fractions:
Next, we must turn the fraction we are dividing by into a reciprocate:
Now we have 
Next, we multiply!:
Simplified:
The answer is 24.........................
