Add the x terms in the two equations and the y terms in the two equations so you get 3x + 8y = 11

Multiply all terms in the top equation by 2 so that you  can eliminate the x terms

Multiply the x in the first equation by -2 so you get -2x + y = 2

Multiply all terms in the top equation by -2 so that you can eliminate the x terms.

Describe the error in solving the system of equations using elimination:

They eliminated the x terms when they should have eliminated the y terms.

The subtracted 5x and x to get 4x, but they should have added the x terms to get 6x = 24.

They added 16 and 8 to get 24, but they should have subtracted them to get 8 on the right side of the equation.

They eliminated the y terms, but they couldn't because one is a negative and one is a positive.
