One-half x + 4

x + 6 minus one-half x minus 2
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
Both expressions equal 6 when substituting 2 for x because the expressions are equivalent.
One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.

Answer:

Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.

Explanation:

x=2

1/2(x) + 4

1/2(2) +4

1+4 = 5

x + 6 -1/2(x) -2

2+6 -1/2(2) -2

8 - 1 -2 = 5

Hope i helped you out :)
