Answer:
Subtraction property of equality
Step-by-step explanation:
Given the equation;
2x + (x+5) = 41
open the parenthesis;
2x+x + 5 = 41 (Associative property)
3x+5 = 41
Subtract 5 from both sides
3x + 5 = 41
3x + 5- 5 = 41 - 5 (Subtraction property of equality)
3x = 36
Divide both sides by 3;
3x/3 = 36/3
x = 12 (Division property of equality)
Hence the required property is Subtraction property of equality
