Erma solves an equation by first subtracting 8 from both sides of the equation. she then divides both sides by 8 and finds the solution. which of the following gives the properties of equality that she used and their correct order?

This is the concept of algebra, to get the inequality we proceed as follows; Erma subtracted 8 from both sides and divided both sides by 8 so that we can get the value of the unknown. The the properties used were:

Subtraction properties of inequality, which states that:
if a<b, then a-c<b-c

Division properties of inequality, which states that:
if a<b, then a/c=<b/c

 

Hold on lemme do the work

Answer is negative 2
