Math plz help!!!!!!!!!!!

Answer 1

I dont know what you want to know but I'll answer all of them.

for a it would be


`3 + 2x`
for c you would exchange the variable x with 5 to find out the price they payed

for d, you would do the inverse operation and first subtract 19 by 3 and get 16. than divide 16 by 2 and you will get x = 8
