Answer:
1. if x + 5 = 12, then x = 7
<u>:Subtraction property of equality</u>
2. If x + y = 20, and y = 5, then x + 5 = 20.
<u>:Substitution property of equality</u>
3. If 2x3 = 11, then 11 = 2x - 3.
<u>:Symmetric property of equality</u>
-4 x = -4 -16 = 4x = -20
divide both sides of the equation by -4
-The answer to your question is 5, or x = 5! Hope this helps
