Hugo took these steps to solve the system of equations.

2 x minus 3 y = negative 11. 3 x + 2 y = negative 5.

Step 1 4 x minus 6 y = negative 11. 9 x + 6 y = negative 15.

Step 2 13 x = negative 26

Step 3 x = negative 2

Step 4 3 (negative 2) + 2 y = negative 5. Negative 6 + 2 y = negative 5. 2 y = 1. y = one-half.

Step 5 The solution is (Negative 2, one-half).

Is Hugo's solution to the system of equations correct? Explain why or why not.

Yes, Hugo's solution is correct.

No, Hugo should have gotten positive 2 in step three.

No, Hugo forgot to multiply both sides of the first equation in step one.

No, Hugo should have subtracted the equations instead of adding them in step 2.
