What numbers can divided to equal 144 which if added will be 7?

Answer 1

151

Answer 2

6.9517 & 0.0483

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
