Let x = one number
y = another number
Equations:
x/y = 144 .............. .....equation (1)
x + y = 7 ....................equation (2)
Multiply eq. (1) by -y:
- y(x/y = 144) -y
-x = -144y
-x +144y = 0 .................equation (3)
By elimination ( Equations 2 & 3)
x + y = 7
-x+144y= 0
=========
0 + 145y = 7
y = 7/145
y = 0.0483
Substitute y = 0.0483 to equation 2
x + y = 7
x + 0.0483 = 7
x = 7 - 0.0483
x = 6.5917
Check:
x/y = 144
6.5917/0.0483 = 144
143.9 or 144= 144
