Answer:

Commutative Property

Step-by-step explanation:

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.

First step: you got to add y to both sides in the math problem Ex: 15x - y + y < 12 + y

Second step: simplify 15x < 12 + y

Third Step: This you got to divide both sides by 15 like this: 15x/15 < 12/15 + y/15

Last and Fourth step: Simplify and thats your answer x < 12 + y/15

Hey there (again)

$x = 2y \\ y = -2 \\ x = 2(-2) \\x= -4 \\ \\ \\ w + xy + 4x^2 = 2\\ w+-4(-2) + 3(-4)^2 = 2 \\ w + 8 + 3(16) = 2 \\ w + 8 + 48 = 2 \\ Subtract56: w + 56 =2 \\ 56 - 56 (Cancel) \\ 2 - 56 = -54 \\ w = -54$

Answer: $B$ the simplification performed in step 2 is invalid or incorrect

Good luck on your assignment and enjoy your day
