Answer:
my apologize for dont really understand the question! but this is what i got
m=p-5n or m=-5n+p
I can't exactly understand what you mean but what I thought you put in the answer is 40
5x + 4 = 7x
Subtract 4 from both sides.
5x = 7x - 4
Subtract 7x from both sides.
5x - 7x = -4
Simplify.
-2x = -4
Divide both sides by -2.
x = 4/2
x = 2
