Three less the product of 9 and a number is 4.

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^

9 x 8 divided by (5-3)=36

1/8 is left? add a bit more info plz
