Answer:
a:b = 14
Step-by-step explanation:
[tex]\dfrac{2a - 3b}{5} =\dfrac{a + b}{3}[/tex]
[tex] 15 \times \dfrac{2a - 3b}{5} = 15 \times \dfrac{a+b}{3}[/tex]
[tex] 3 \times (2a - 3b) = 5 \times (a + b) [/tex]
[tex] 6a - 9b = 5a + 5b [/tex]
[tex] a - 9b = 5b [/tex]
[tex] a = 14b [/tex]
[tex] \dfrac{a}{b} = 14 [/tex]
