Answer:
n = -2
Step-by-step explanation:
6(2n - 3) - 2(6n + 1) = 10n
multiply the brackets
6*2n - 6*3 - 2*6n - 2*1 = 10n
12n - 18 - 12n - 2 = 10n
add or subtract the like terms
0 - 20 = 10n
shift 10 to the right hand side .REmember when u shift multiplication changes to division.
-20 / 10 = n
-2 = n
Answer:n=-2
12n-18-12n-2=10n
-20=10n
n=-2

Answer: 14+x=17
when you do this you can put whatever letter you want but sum is adding so this is why it came out as it did
