Let one number be x and the other number be y.
The 2 equations are:
x - y = 0.6 --------------- (1)
x/y = 0.6 --------------- (2)
From equation (1):
x - y = 0.6
x = 0.6 + y --------------- Sub into (2)
[tex] \dfrac{0.6 + y}{y} = 0.6[/tex]
0.6 + y= 0.6y
y - 0.6y = - 0.6
0.4y = - 0.6
y = -0.6 ÷ 0.4
y = -1.5
Sub y = -1.5 into (1):
x - y = 0.6
x - (-1.5) = 0.6
x + 1.5 = 0.6
x = 0.6 - 1.5
x = - 0.9
Answer: The numbers are -0.9 and -1.5

x - (-1.5) = 0.6
x + 1.5 = 0.6
x = 0.6 - 1.5
x = - 0.9
Answer: The numbers are -0.9 and -1.5
