Given the numerical expression:
8-4n+9n+7+10n
Simplify.
Solution:
In order to simplify the numerical expression, we simply need to combine like terms.
= 8-4n+9n+7+10n
= 15 + 15n
We can solve the value of n by transposing 15 on the other side of the equation, note that when transposing a number, the sign changes.
15n = -15
Divide both sides by 15 in order to get the value of n.
n = -1
Final answer:
Simplified form: 15 + 15n
n = -1
