What do you predict happens to the seismic waves as they travel the three different layers of the mantle?

Seismic waves from an earthquake's focus travel through the earth along bent paths and are eventually recorded by distant seismograph stations. ... This indicates that P-waves slow down in the outer core, suggesting that this layer has a significantly different composition from the mantle and may actually be liquid.

Explanation:

hope this helps:)

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
