Answer:
Step-by-step explanation:
For this problem, I'm pretty sure its asking you for the lcm of 12 and 14. It asks for how many photograghs (x) will be sold on each site, when the amount of money is the same (y).
The lcm of 12 and 14 is 84, so that means that Jessa will sell 7 paintings on the first site, and 6 on the second.
Hope this helps!!
