A checking account is set up with an initial balance of $4800, and $400 is removed from the account each month for rent (no othe
r transactions occur on the account). Write an equation whose solution is the number of months, m, it takes for the account balance to reach $2000. (You do not need to solve the equation).
So we would have to multiply the "2x - 8" by 5 each resulting in 10x - 40 + 15. Then we subtract which results in 10x - 25 = - 15. We add 25 to 25 and 15 resulting in 10x = 10. We divide each by 10 which results in x = 1.
