If the value of 3A + 6B has nothing to do with the value of X Given that a = 2x square + 3xy-2x-1, B = - x square + XY-1, and 3a + 6B value is independent of X, find the value of Y Simplify to X (15y-6) - 9, the answer is: y = 0.4

If the value of 3A + 6B has nothing to do with the value of X Given that a = 2x square + 3xy-2x-1, B = - x square + XY-1, and 3a + 6B value is independent of X, find the value of Y Simplify to X (15y-6) - 9, the answer is: y = 0.4

Pay attention to deeply understand the meaning of "nothing to do with X"
X (15y-6) - 9, which is independent of X, means that no matter what value x takes, the value of this formula remains unchanged
Therefore, if and only if the value in brackets is zero, the above effect can be achieved
