C. the subtraction property of equality
Step 1 involves subtracting 11x from both sides of the equation to isolate the term with x on one side. This is an application of the subtraction property of equality, which states that if you perform the same operation on both sides of an equation, the equation remains true.
What is the justification for step 1 in the solution process?
8x + 15 = 11x + 2
Step 1: 8x = 11x − 13
