Think the 4 less than but not equal to as a equal sign step 1. isolate the variable ( variable must stand alone) step 2. subtract 12n -12n=0 step 3. since you subtract 12n from the left you must do the same to the right. step 4. 13n - 12n =1n step 5. the equation should look like this -4 less than but not equal to 1n step 6. isolate the variable n step 6. divide 1n/1 on the right and on the left -4/1 it equals -4 so, n is -4
