Answer:
a : b = 19 : 7
Step-by-step explanation:
Given
4a - 5b : 5a + 4b = 1 : 3
Expressing in fractional form, that is
=
( cross- multiply )
3(4a - 5b) = 5a + 4b ← distribute left side
12a - 15b = 5a + 4b ( subtract 5a from both sides )
7a - 15b = 4b ( add 15b to both sides )
7a = 19b ( divide both sides by 7 )
a =
b ( divide both sides by b )
= ![\frac{19}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B7%7D)
That is a : b = 19 : 7
