analyse the negative effect of people's views about infections diseases on the health and safety of people

Because having an infectious disease carries a stigma, people are less likely to disclose their disease status and are less likely to get treatment because they are afraid someone will find out that they are infected. This failure to disclose, coupled with unsafe practices, causes the disease to spread.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
