Solve the system of equations. 2x+2y+3z=4 5x+3y+5z=5 3x+4y+6z=5

B.

Step-by-step explanation:

Consider the system of three equations:

Multiply the first equation by 5, the second equation by 2 and subtract them:

Multiply the first equation by 3, the second equation by 2 and subtract them:

Multiply the third equation by 2 and add the second and the third equations:

Fro mthe third equation

Substitute it into the second equation:

Substitute y=20 and z=-14 into the first equation:

The solution is

he is going to fill two shelves and the third shelf will only have five video games

17,000 is the correct answer.
