Step-by-step explanation:
3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
