Solve for n (look at attachment)

First distribute 6 into the parenthesis so that would be (6n - 18) - 2n = 10. Then erase the parenthesis to make the subtraction easier. So that would be 6n-18-2n=10. Then solve the subtraction by separating the unknown numbers with n and the normal numbers. So 6n-2n=4n 4n-18=10. To find n, add 18 and 10 to make both sides of the equation equal. So that would make 4n=28. Therefore n would be 7 because 28 divided by 4 makes 7.
