    X + (2x/3 - 2) = 103 : Write the expression.

    x + 2x/3 - 2 = 103 : Remove parentheses.

    (x + 2x/3 - 2) * 3 = 103 * 3 : Multiply both sides by 3 to remove the fraction.

    3x + 2x - 6 = 309 : Evaluate.

    5x - 6 = 309 : Combine like terms

    5x - 6 + 6 = 309 + 6 : Isolate x by adding 6 to each side.

    5x / 5 = 315 / 5 : Divide by x to find its value.

    x = 63.

    63 is one of the number. Now, find the second number using its quantity.

    2x / 3 - 2

    2 (63) / 3 - 2

    126 / 3 - 2 = 40.

    One of the numbers is 63, and the other number is 40.

    X = 2/3y - 2

    x + y = 103

    2/3y - 2 + y = 103

    2/3y + y = 103 + 2

    5/3y = 105

    y = 105 * 3/5

    y = 315/5 = 63

    x + y = 103

    x + 63 = 103

    x = 103 - 63

    x = 40

    so ur 2 numbers are : 63 and 40
