The answer (usually called the 'solution') is the one and only number that 'n' can be if that equation is a true statement. Here's a suggestion of a procedure you can use to find it:
<u>1.8 + 7n = 9.5 - 4n</u>
Add 4n to each side: 1.8 + 11n = 9.5
Subtract 1.8 from each side: 11n = 7.7
Divide each side by 11 : <em> n = 0.7</em>
It's -5.25 because 5*8 is 40 and 6*8 is 48.
To find the gcf you have to wright down the factors of both the numbers, all of them. Then, find the one that is the greatest number, but both 36 and 27 have, which would be 9
