Answer:
C.
the subtraction property of equality
Step-by-step explanation:
Given
8x + 15 = 11x + 2
Subtract 15 from both sides of the equation
8x + 15 - 15 = 11x + 2 - 15
8x = 11x - 13
Answer:
the addition property of equality
Step-by-step explanation:
Compare step 1 with step 2 in the solution process:
step 1: -5x = -4x - 15
step 2: -x = -15
The variable was isolated on the left side of the equation by adding 4x to both sides. This is justified by the addition property of equality.
