    y = 1

    x = 5

    Step-by-step explanation:

    Substitute:

    2 (2 + 3y) + 3y = 13

    Simplify:

    4 + 6y + 3y = 13

    Combine terms:

    4 + 9y = 13

    Subtract 4 from each side:

    9y = 9

    Divide by 9:

    y = 1

    Substitute:

    x = 2 + 3 (1)

    Simplify:

    x = 2 + 3

    Combine terms:

    x = 5

    Check with original equation:

    2 (5) + 3 (1) = 13

    Simplify:

    10 + 3 = 13

    Combine terms:

    13 = 13

    It works!

    Step-by-step explanation:

    Given that

    2x+3y=13. Equation 1

    x=2+3y. Equation 2

    Using substitution method

    Substitute x in equation 2 to equation 1

    2x+3y=13

    2 (2+3y) + 3y=13

    4+6y+3y=13

    4+9y=13

    9y=13-4

    9y=9

    y=9/9

    y=1.

    To get x, substitute y=1 into equation 2

    x=2+3y

    x=2+3 (1)

    x=2+3

    x=5

    Then, x=5 and y=1 is the solution to the simultaneous equation
