    Answer:

    x = 3

    y = 3

    (3,3)

    Step-by-step explanation:

    Let’s solve for y.

    6x−5y=3

    Step 1: Add -6x to both sides.

    6x−5y+−6x=3+−6x

    −5y=−6x+3

    Step 2: Divide both sides by -5.

    −5y
    /−5
    =
    −6x+3
    /−5

    y=
    6
    /5
    x+  −3
    /5

    Let’s solve for y.

    5x−6y=−3

    Step 1: Add -5x to both sides.

    5x−6y+−5x=−3+−5x

    −6y=−5x−3

    Step 2: Divide both sides by -6.

    −6y
    /−6
    =
    −5x−3
    −6

    y=
    5
    /6
    x+
    1
    /2

    (Now let’s solve for (x,y))

    Solving for x =

    5/6x+1/2=6/5x+−3/5

    Step 1: Subtract 6/5x from both sides.

    5
    /6
    x+
    1
    /2
    −
    6
    /5

    x=
    6
    /5
    x+
    −3
    /5
    −
    6
    /5
    x

    −11
    /30
    x+
    1
    /2=
    −3
    /5

    Step 2: Subtract 1/2 from both sides.

    −11
    /30
    x+
    1
    /2
    −
    1
    /2
    =
    −3
    /5
    −
    1
    /2
    −11
    /30

    x=
    −11
    /10

    Step 3: Multiply both sides by 30/(-11).

    (30
    /−11
    )*(
    −11
    /30
    x)=(
    30
    /−11
    )*(
    −11
    /10
    )

    x=3

    Solving for Y:

    y = 5/6(3)+1/2

    y = 3
