Everything underlined means its a fraction/divided hope this helps <em>:D</em>
Answer:
M = 42
Step-by-step explanation:
Ooo..I'm actually good at these!!
So its simple...All you do is take the equation and divide both sides by 4.5
When we divide, we get m alone.
4.5m = 189
/4.5 /4.5
m = 42
Hope this helps!! Can I have brainliest please?!?

Answer:
(2,-3)
Step-by-step explanation:
I am not sure if you meant the first equation to be y or -y. I solved it as y.
y = x-5 -x -3y =7
I am going to take the second equation and write it as x =
-x - 3y = 7 Give equation
-x = 3y +7 Add 3y to both sides
x = -3y-7 Multiplied each term in the equation by -1 so that x could be positive
I am going to substitute -3y-7 for x in the first equation up above
y = x - 5
y = -3y -7 - 5 Substitute -3y-7 for x
y = -3y -12 Combined -7-5
4y = -12 Added 3y to both sides
y = -3 Divided both sides by 4.
I now know that y is -3, I will plug that into x = -3y-7 to solve for x
x = -3(-3) -7
x = 9-7 A negative times a negative is a positive
x = 2
