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
