    Answer:

    Answer:

    -510 and -600

    Step-by-step explanation:

    \begin{gathered}\text{Given ratio of numbers = 17:20}\\\\\text{Let the 2 numbers be 17x and 20x.}\\\\\text{According to question,}\\\\17x – 20x = 90\\\\\implies -3x = 90\\\\\implies x = – \dfrac{90}{3}\\\\\\\implies x = \boxed{- 30}\\\\\textbf{Verification:}\\\\\text{Put x = -30 in 17x-20x = 90}\\\\17(-30) – 20(-30) = 90\\\\\implies -510 – (-600) = 90\\\\\implies -510 + 600 = 90\\\\\implies 90 = 90\\\\\implies L.H.S. = R.H.S.\\\\\text{Hence, verified the value of x.}\\\\\end{gathered}

    Given ratio of numbers = 17:20

    Let the 2 numbers be 17x and 20x.

    According to question,

    17x−20x=90

    ⟹−3x=90

    ⟹x=−

    3

    90

    ⟹x=

    −30

    Verification:

    Put x = -30 in 17x-20x = 90

    17(−30)−20(−30)=90

    ⟹−510−(−600)=90

    ⟹−510+600=90

    ⟹90=90

    ⟹L.H.S.=R.H.S.

    Hence, verified the value of x.

    \text{The 2 numbers are 17(-30) = -510 and 20(-30) = -600.}The 2 numbers are 17(-30) = -510 and 20(-30) = -600.

    Hope it helps.
