N=4
4n-6 (n-2) = -24 + 7n
You first multiply the six with the equation in the parentheses making it:
4n-6n + 12= -24 + 7n
You then subtract 4n from -6n changing it to:
-2n + 12 = -24 + 7n after that you switch the 12 and 7n so that the equation can be
-2n -7n = -24 - 12
After that combine the numbers together:
-9n = -36
Then divide both sides by -9 making
n= 4
