Step-by-step explanation:
#1
- a + 10 = 20 ⇒ subtract 10 form both sides ⇒ a = 10
- Subtraction property of equality
#2
- 4x - 5 = x + 12 ⇒ add 5 to both sides ⇒ 4x = x + 17
- Addition property of equality
#3
- 5(x + 7) = -3 ⇒ multiply 5 to both terms ⇒ 5x + 35 = - 3
- Distributive property of multiplication
#4
- If AB = BC and BC = CD, then AB = CD
- Transitive property of equality
