• She used the Distributive Property to get 4x − 12 − 2y = 4y − 6.

• She subtracted 2y from each side to get 4x − 12 = 2y − 6.

• She added 6 to each side to get 4x − 6 = 2y.

• She divided both sides by 2 to get y = 2x − 3.

• yes

• no

James has a dog-grooming service. He charges a flat rate of $50 per month, plus $10 per grooming. Bradly does not charge a monthly fee for his dog-grooming service, but he charges $35 per grooming. Write and solve an equation to find the number of grooming visits w for which James and Bradly would charge the same amount. Enter the number only.
