Linear Equations Practice Test

Refer to the image. What error did the student make when solving this system of equations?

• They should not have added -27 and 20 to get -7

• They multiplied the -2y by -2 when they should have multiplied -2y by 2 to get -4y

• They should have multiplied the first equations by -2 instead of -3

• No errors; everything looks fabulous to me.
