I think the answer is 0.77
The first step is to set up an equation, 9•n -3 =4
Isolating the variable you’ve chosen (x,y,z, etc.) is your main goal.
9•n -3 =4
+3. +3
= 9•n =7
/9. /9
=0.777777777
To isolate variable n you need to add 3 to both sides, then divide both sides by 9, to get 0.7777777777. Definitely round the answer.
Hope I helped ^u^
