    x=10 and W=12

    Step-by-step explanation:

    Let's solve the equations. First we need to understand that the problem can be solved because we have two variables (x, W) and two equations.

    Now, we have the following equations:

    3x+3W-66 making the equation equal to 0:

    3x+3W-66=0 which can be express as:

    3x=-3W+66

    x = (-3W+66) / 3

    x=-W+22 (equation 1)

    The next equation is:

    12x+15W-300 making the equation equal to 0 and then divided by 3:

    (12x+15W-300) / 3=0 which is:

    4x+5W-100=0 (equation 2), using equation 1 we can write:

    4 (-W+22) + 5W-100=0

    -4W+88+5W-100=0

    W-12=0

    W=12

    Using W=12 in equation 2 we have:

    4x+5W-100=0

    4x+5 * (12) - 100=0

    4x + (60) - 100=0

    4x-40=0

    4x=40

    x=40/4

    x=10

    In conclusion the solution for the equations are: x=10 and W=12.
