Answer 2

Step-by-step explanation:

-x sq ÷4-2y

x sq ÷4-2yX=6&y=2

x sq ÷4-2yX=6&y=2-6 sq÷4-2(2)

x sq ÷4-2yX=6&y=2-6 sq÷4-2(2)-6sq÷4+4

x sq ÷4-2yX=6&y=2-6 sq÷4-2(2)-6sq÷4+4-6sq÷8

x sq ÷4-2yX=6&y=2-6 sq÷4-2(2)-6sq÷4+4-6sq÷8square of 6=12.

x sq ÷4-2yX=6&y=2-6 sq÷4-2(2)-6sq÷4+4-6sq÷8square of 6=12.12÷8

x sq ÷4-2yX=6&y=2-6 sq÷4-2(2)-6sq÷4+4-6sq÷8square of 6=12.12÷8=2/3 is your answer..
