It’s 14 and 70
Assume one part is x, and since the other part is 5 times the first part it becomes 5x. Then add those two together to get 84.
And it becomes 5x+x=84
Which simplifies to 6x=84, then divide both sides by 6 to get x=14
So the first part is 14, and the second part is five times the first part which is 5*14 which equals 70.
