An igneous rock with small crystals (fine texture) cooled: 1 - rapidly from magma on the Earth's surface.

2 - rapidly beneath the surface.

3 - slowly from magma inside the Earth's crust

4 - unknown. It is not possible to tell the rate of cooling from the crystal size.

To solve this system of equations by elimination, what operation could be used to eliminate the y-variable and find the value of x? 6x + 5y = 2 4x + 2y = 8 a) subtract 2 times the second equation from 3 times the first equation b) subtract 3 times the second equation from 2 times the first equation c) subtract 5 times the second equation from 2 times the first equation d) subtract 2 times the second equation from 5 times the first equation
