Examine Kaitlyn’s steps for solving the system of equations. –3x + 2y = 8
3x + 2y = –6

Step 1: 4y = 2

Step 2: y = 2

Step 3: –3x + 2(2) = 8

Step 4: –3x = 4

Step 5: x = –1.333

Kaitlyn found the solution to be (1.3, 2). Is her solution correct? Explain.

Yes, she correctly solved the system of equations.
No, she made an error in step 1. The y variable should have been eliminated when adding the system of equations.
No, she made an error in step 2. She should have found y = 0.5.
No, she substituted y into the wrong equation to solve for x in step 3.
