X - y = 2
4x - 3y = 11.
Using Elimination method, eliminating x, multiply equation (i) by 4. Because of the 4 in the second equation.
x - y = 2 ... (x4)
4x - 3y = 11.
4x - 4y = 8
4x - 3y = 11.
The first minus the second.
(4x - 4x) -4y- -3y = 8-11
-4y + 3y = -3
-y = -3. Divide both sides by -1
y =3.
Substitute this value into the very first equation
x - y = 2, y = 3
x - 3 = 2
x = 2 + 3 = 5.
Therefore x = 5, y = 3.
I would describe how theres space. Because there is no shape of water do molecules are more spaced out. I think that's how it is.
