Question

Benjamin solved the equation 3 + x over 2 = 10 and justified each step as shown.

Identify Benjamin’s error and fix his mistake

Step:
3 + x/2 = 10
X/2 = 7
X= 14

Justification:
Given
Multiplication Property of Equality
Subtraction Property of Equality

Answer 1

The equation itself is fine but the justification looks wrong step2 is subtraction property of equality and step3 is Multiplecation property of equaliity

I could be wrong but im 95% sure

Good luck!

Answer 2

The method of solving this equation looks fine to me and the answer is correct since 3 + x/2=10 is x/2=10-3 and so x/2 =7 and so x = 14 as shown and checking, then subsituting 14 for x then x/2=7 = 10-3 so therefore it is fine the way it is.
