Answer 1

x=5y
x-5=15(y-5)

Answer 2

is the equation x-5=15(x-5)

Answer 3

or is it 5x-5=15(x-5)

Answer 4

let David's present age = x years
then Polaski's age = 5x years

five years ago
Davidf's age = x-5
Polski's age = 5x -5

ATQ 5x -5 = 15(x-5)

5x - 5 = 15x -75

Answer 5

ty

Answer 6

5x - 15x = -75 +5
-10x = -70
