  1. Answer:

    Question

    ❇️solve x – y = 1 & 2x + y = 8

    Solution ⬇️

    ✍️By substitution method

    ✍️x-y=1..(1)

    ✍️2x+y=8..(2)

    _____________

    ️3x=9..(Adding equation 2 and 1)

    _____________

    [tex] = = > 3x = 9 \\ = = > x = \frac{9}{3} = 3[/tex]

    • Substituting value x=3 in equation 1

    ✍️x-y=1..(1)

    ✍️3-y=1..(x=3)

    ✍️-y=1-3

    ✍️-y=-2

    ✍️y=2

    ️ (x,y)(3,2) is the solution of the given quadratic equation

    Step-by-step explanation:

    hope you appreciate this ans
