Given the numerical expression:
3(n + 4)
Determine what is it equivalent to.
Solution:
In order to determine what the expression is equivalent to, we distribute 3 to each value inside the parenthesis.
= 3 (n + 4)
= 3n + 12
If we want to solve n, then we can transpose 12 on the other side of the equation, note that when transposing a number, the sign changes.
3n = -12
Divide both sides by 3 in order to get the value of n
n = -4
Final answer:
Simplified form: 3n + 12
value of n: -4
