Eq1: X = 5y + 3.

Eq2: X = 5y - 3.

Substitute 2 for Y in each Eq and solve

for X:

Eq1: X = 5*2 + 3 = 10 + 3 = 13.

Eq2: X = 5*2 - 3 = 10 - 3 = 7.

The value of the 1st term in each Eq is 10. In Eq1, we add 3 to 10. But in Eq2,

we subtract 3 from 10. Therefore, the

solutions cannot be the same.
