distribute the multiplication on the right half and rearrange and you'll get a quadratic
2050 = 3n^2 + 10n
3n^2 +10n - 2050 = 0
Solve with the quadratic formula
2050 = 3n^2 + 10n
3n^2 +10n - 2050 = 0
Solve with the quadratic formula
-
2050 = 3n [n+(10/3)]
expand the brackets
2050 = 3n^2 + 10n
rewrite it as
3n^2 + 10n - 2050 = 0
use the quadratic formula
n = (-10 +/- sqrt(100 - 4*3*-2050))/6 = (-10 +/- sqrt(24700))/6 = 24.53 or -27.86

2050 = 3n + (n + 3.3333)
2050 - n + 3 3333 = 3n
683.333 - n/3 = n
BOO! cba
2050 - n + 3 3333 = 3n
683.333 - n/3 = n
