Kaitlyn found the solution to be (1.3, 2). Is her solution correct? Explain.
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
O Yes, she correctly solved the system of equations.
O No, she made an error in step 1. The y variable
should have been eliminated when adding the
system of equations.
O No, she made an error in step 2. She should have
found y = 0.5.
O No, she substituted y into the wrong equation to
solve for x in step 3.
