Answer:
m = 25/9
Step-by-step explanation:
To solve for m, we must make the equation look like m=?
Since m is divided by 54, we can multiply both sides by 54 to make it have a coefficient of 1. So now our equation looks like:
m = 5/9 * 5
So m = 25/9
I would assume that since -4 is being divided by 0 that your answer is undefined.
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
