    Answer:

    X=0

    Y=10

    Step-by-step explanation:

    3x+2y=20——–(1)

    2x+3y=30——–(2)

    (1)x2 => 6x+4y=40———(3)

    (2)x3 => 6x+9y=90———(4)

    (3)-(4)

    6x-6x+4y-9y=40-90

    0-5y =-50

    5y=50

    y=50/5

    Y=10

    Substitute y=10 in equation (1) or (2) you will get x answer

    Sub in equation (1)

    3x+2(10)=20

    3x+20=20

    3x=20-20

    3x=0

    X=0

    Answer:

    24

    Step-by-step explanation:

    3x + 2y = 20 Equation No.1

    2x + 3y = 30 Equation No.2

    Multiply 1st Equation By 3 And Multiply 2nd Equation By 2

    We Get 9x + 6y = 60 Equation No.3

    And 4x + 6y = 60

    Subtract Them

    Then We Got Ans. 24
