How do Sylvia and Mrs. Tilley feel about each other in the passage?

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

they are direct opposites. they can both be corrupted. they are inseparable.

the answer would be $18.75.

all you have to do is multiply 125 times 0.15 to get your answer

hope this (rate me brainliest ! )
