List the 3 types of rocks and explain how each is formed pls

Igneous Rocks- Forms when magma cools and come solid

Sedimentary Rocks- Made from small grains of particles that are carried from air, wind, gravity, water, or ice. Formed from those sediments cementing together.

Metamorphic Rocks- Formed by heat and pressure

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.
