x=10 and W=12
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:
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
Using W=12 in equation 2 we have:
4x+5 * (12) - 100=0
4x + (60) - 100=0
In conclusion the solution for the equations are: x=10 and W=12.
