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>
