M=3n
divide both sides by 3
M/3=3n/3
on the left hand side, the numerator constant cuts the denominator 3
therefore, n=M/3

Step-by-step explanation:
Answer:
1.1587855e+30
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":
Subtract y from both sides:
Now, substitute "5-y" for "x" in the first equation:
Note that:
Cancel out like terms:
Subtract 25 from both sides:
Divide both sides by -10
Now, substitute this value back into either of the equations to solve for x.
Add 15/2 to both sides:
Now, find the difference:
Answer:
-3y+15
Step-by-step explanation:
2y - 5(y - 3)
To simplify, the first step is to distribute the -5
2y - 5y +15
Combine like terms
-3y+15
