Brainiest and lots of points the set {1,2,3,…42} is split into two sets a and b. how many ways are there to do this so that a and b have the same sum of elements? need now

  zero

Step-by-step explanation:

In order for sets A and B to have the same sum of elements, that sum of elements must be the same for each set, and half the sum of elements of the original set.

The sum of elements of the set {1, 2, 3, ..., 42} is an odd number (903), so there cannot be two sets with the same sum that have that total.

y = 0.77(x)
