If -8x - y = –2 and 10x – 6y = 9 are true equations, what would be the value
of -18x + 5y?

Would a graph help?

Step-by-step explanation:

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
