Which expression is represented by the model?

4x-3

Step-by-step explanation:

I have never worked with the program you are using, but if i were to assume,

there are four Xs (4x) and three minus signs, (-3)

so 4x-3 make the most sense to me.

i hope this helps!

:)

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0
