Answer:
On simplification of above expression, n = 10.
Explanation:
Here, the given expression is : 3(7 + 4n) = 41 +10n
by DISTRIBUTIVE PROPERTY:
A ( B + C ) = AB + AC
Now, here simplifying the expression,
3(7 + 4n) = 41 +10 n ⇒ 3(7) + 3(4 n) = 41 + 10 n
or, 21 + 12 n = 41 + 10 n
or, 12 n - 10 n = 41 - 21
or, 2 n = 20
⇒ n = 20 / 2 = 10
or, n = 10
Hence, on simplification of above expression, n = 10.
