The solution of system is x=14, y=37
Step-by-step explanation:
Given equations are:
-4y = -64 - 6x => 6x-4y=-64 Eqn 1
4x - 4y = -36 Eqn 2
Subtracting equation 2 from eqn 1
![(6x-4y)-(4x - 4y) = -36+64\\6x-4y-4x+4y=28\\2x=28\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{28}{2}\\x=14\\Putting\ x=14\ in\ equation\ 1\\-4y=-64-6(14)\\-4y=-64-84\\-4y=-148\\Dividing\ both\ sides\ by\ -4\\\frac{-4y}{-4}=\frac{-148}{-4}\\y=37](https://tex.z-dn.net/?f=%286x-4y%29-%284x%20-%204y%29%20%3D%20-36%2B64%5C%5C6x-4y-4x%2B4y%3D28%5C%5C2x%3D28%5C%5CDividing%5C%20both%5C%20sides%5C%20by%5C%202%5C%5C%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B28%7D%7B2%7D%5C%5Cx%3D14%5C%5CPutting%5C%20x%3D14%5C%20in%5C%20equation%5C%201%5C%5C-4y%3D-64-6%2814%29%5C%5C-4y%3D-64-84%5C%5C-4y%3D-148%5C%5CDividing%5C%20both%5C%20sides%5C%20by%5C%20-4%5C%5C%5Cfrac%7B-4y%7D%7B-4%7D%3D%5Cfrac%7B-148%7D%7B-4%7D%5C%5Cy%3D37)

Steps on finding the volume of water :
1. volume . pour enough water from your cup into the graduated cylinder.
2. density . calculate the density by using the formula D=M/V . record the density in (g/m ) ^3 .
3. identify the samples . compare the values for density you calculated to the values in a chart.
