The sum of 12 and one third of n is 1 more than twice n. Express the statement in the form of an equation
12n - 6 = 0
3n - 12 = 0
2n - 35 = 0
5n - 33 = 0
स्पष्टीकरण
12 = \(\frac{n}{3} - 2n = 1\), multiply through by 3
36 + n - 6n = 3
-5n = 3 - 36
-5n = -33
-5n + 33 = 0
5n - 33 = 0
36 + n - 6n = 3
-5n = 3 - 36
-5n = -33
-5n + 33 = 0
5n - 33 = 0
