The distributive property was used to move from step 1 to step 2, by multiplying 5 with each term inside the parentheses to get 5x - 35 = 55. therefore, option A is correct
The property used in moving from step 1 to step 2 in the equation is the distributive property. This property allows the multiplication of a single term by each term inside a set of parentheses. The equation starts with 5 (x minus 7) = 55, and applying the distributive property, we multiply 5 by x and 5 by -7, which gives us 5x - 35 = 55. Therefore, the correct answer is the distributive property, which was used to distribute the multiplication of 5 across the terms within the parentheses.
