If you scroll up I answered a previous question like this in the same subject
The letter c is the correct answer.
Answer:
Difference in large and small numbers, higher or smaller value.
-6.4(x-2.25)=19.2
-6.4*x=-6.4x -6.4*-2.25=14.4
rewrite
-6.4+14.4=19.2 subtrac 14.4 from both sides 19.2-14.4=4.8 rewrite
-6.4x=4.8 divide -6.4 from both sides 4.8/-6.4=.75
x=0.75
Help this helps have a nice nite!
You could solve this mathematically but i mean you could use your eyes.... Its most likely C
