How to solve the equation 11x + 33-3x = 96?

11x+33-3x=96
8x=96-33
8x=63
x=63/8

It is known that 4x-3y-6z = 0, x + 2y-7z = 0, and X, y, Z are not zero. Find the value of 3x + 2Y + ZX + 2Y + 3Z

To solve the system of linear equations 4x − 3Y − 6Z = 0x + 2Y − 7z = 0 with respect to X and y, we obtain x = 3zy = 2Z. Substituting x = 3Z, y = 2Z into the original formula = 9z + 4Z + z3z + 4Z + 3Z = 75

Solve the equations (x + 1) / 5 = (Y-3) / 2 3x + 4Y = 32

(x+1)/5=(y-3)/2
2(x+1)=5(y-3)
2x-5y+17=0.(1)
3x+4y=32.(2)
(1) * 3 - (2) * 2
6x-15y+51=0
6x+8y-64=0
-23y+115=0
y=5
Substitute the result into (1)
x=4

(4x^2-y^2)/(x^2-4y^2)-(2x-y)^2/(x^2-4y^2)-(2y^2-4xy)/(x^2-4y^2)=?
Such as the title

The common factor is first mentioned and then simplified
Original formula = (2x-y) (2x + y-2x + y + 2Y) / (x ^ 2-4y ^ 2)
=(2x-y)*4y/(x^2-4y^2)=(8xy-4y^2)/(x^2-4y^2)
