Three adult and three child movie tickets were purchased for $75. The cost of each child ticket is $3 less than the cost of an adult ticket. The first step to solving this problem algebraically is to write an equation: 3(x + x - 3) = 75 where z represents the cost of an adult ticket. Identify the next step, which would simplify the equation before solving for the variable. (1 point)
