Tell whether the statement below is always, sometimes, or never true. Equation like, a + 4 = 8 and 4 - m = 2 have exactly one solution.

a + 4 = 8

a = 4

Can you add anything else to 4 to get 8? No.

4 - m = 2

-m = -2

m = 2

Can you subtract anything besides 2 from 4 to get 2? No.

So the statements are always true.
