Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.
Step-by-step explanation:
The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.
If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.
The given expression is,

Use multiplication property of equality, multiply 5 both sides,


Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.
