Answer:
n = 4
Step-by-step explanation:
3 + 4n + n = 2n +15
3 + 5n = 2n + 15
5n - 2n = 15 - 3
3n = 12
n = 12 / 3
= <u>4</u>

Answer:y=3/20+12m+6
Step-by-step explanation: The equation for these types of problems are y=mx+b
the y is the second number, so in the first one the y would be -6, so you replace the y with the -6 and the x with -12
so now the equation is -6=-12m+b
you add the -12m to the other side to make 12m+6=b
now onto the second one, the 9 is the y and the 8 is the x, now the equation is 9=8m+b
this time you replace the b with the equation you got earlier (12m+6=b)
So the equation is 9=8m+12m+6
minus the 6 on both sides
3=8m+12m
add the m's
3=20m
3/20=m
Now you replace the m and the b
y=3/20x+12m+6
