-3 =-2x - 7

4=-2x
Divide by -2
-2 = x
Im guessing your saying how do you write 1.92 x 10 when you multiply you dont need to line up your decimals but it would lookm something like this:
1.92
x 10
and if it was 1.92 and 10.0 it would look like this
1.92
x 10.0
the deimals dont line up because you are multipling but if you were adding or subtrcating then you would have to line it up but not in this case

Answer:
The answer is 5:12
Step-by-step explanation:
It is 5:12 because We already know that 7 pens are blue. To find the number of red pens we must subtract 12 - 7 and get 5 as the number of red pens. Now knowing the no. of red pens and total number we can say the ratio of red pens to total no. is 5:12
