Step-by-step explanation:
cynthia can wallpaper a room 4 hours with means in 1 hour she can wallpaper 1/4th of the room, her brother can wallpaper the same room in 6 hours so I'm 1 hour he can wallpaper 1/6 of the room.
Im assuming you meant 43 because if you did x=5
8 times 5 is 40 and ifyou add 3 it equals 43
Answer:2x+8=2
2x=2-8
2x= -6 (devide both sides by 2 to get x)
2x/2 and -6/2
×=3
