Why teachers should wear uniforms

Uh teachers don't wear uniform they come to school in a casual dress

I think it's because uniforms provide a sense of belonging it makes them feel that they belong to a certain school.it would treat principals,teachers and pupils equally.and it's also good if they wear uniforms as it will make them all equal and not promote competition of dresscodes among teachers.and moreover some casual wear isn't too appropriate for the students as they can be disturbed in there learning.

I hope this helps

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
