    Answer:

    Sure

    Step-by-step explanation:

    Here,

    2x+3y = 1

    or, y = x-8

    Now,

    x 9 10 11

    x 9 10 11 y 1 2 3

    Substitute y=x-8 into the first equation

    2x+3(x-8)=1

    Expand

    2x+3x-24=1

    Collect like terms

    5x-24=1

    Move negative 24 to the other side as a positive number

    5x= 25

    Divide both sides by 5

    25/5 is 5

    Therefore x is equal to 5

    Sub x equal five in second equation

    y=5-8

    5-8= -3

    Therefore, y is equal to -3

    Therefore, x is equal to 5 and y is equal to -3
