Solve for y.

Solve for z.

x + y + z = 4

4x - y - z = 1

x + z = 2

x = 1, y = 2, z = 1

Step-by-step explanation:

Adding the first 2 equations to each other gives

x + y + z + 4x - y - z = 4 + 1

which simplifies to

5x = 5, so x = 1

x + z = 2 so 1 + z = 2, so z = 1 too

x + y + z = 4 = 1 + y + 1 = 2 + y so y = 2

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
