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 x represents the cost of an adult ticket. Identify the next step,
which would simplify the equation before solving for the variable.
1 answer
The next step would be to distribute the 3 to the terms inside the parentheses. The equation would become 3x + 3(x - 3) = 75.
