Question

Step 1: 6 – 7 + 3x − 2x + 4y − y
Step 2: (6 − 7) + (3x − 2x) + (4y − y)
Step 3: −1 + x (3 − 2) + y (4 − 1)
Step 4: −1 + x (1) + y (3)
Step 5: −1 + x + 3y
Which statement is correct?
Step 2 uses associative property of addition, and step 3 uses distributive property of addition.
Step 1 uses commutative property of addition, and step 5 uses associative property of addition.
Step 2 uses distributive property of addition, and step 4 uses commutative property of addition.
Step 4 uses associative property of addition, and step 3 uses commutative property of addit
