What is the greatest common factor of 36x and -20??

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

b). 4320 have a nice day

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
