1. Subtract the second equation from the first equation:

(X + 3y) - (X + 2y) = 4 - 4

X + 3y - X - 2y = 0

y = 0

2. Substitute y = 0 into the second equation:

X + 2(0) = 4

X = 4

Correct [Solution]: (4,0)

Which statement best describes the key changes in perspectives on inclusion? An inclusive program must consider the unique experiences of every child and family as well as the child's strengths and needs. There is a shift in thinking about individual programs as "inclusive programs" to thinking about inclusion as something that reflects the cultural influence of the family. There is a greater emphasis on barriers to full participation and the acknowledgement that all children are unique and must be fully and meaningfully engaged in a program. In an inclusive program all participants are accepted by their peers and other members of the community.
