Answer:
none of them.
Step-by-step explanation:
The substitution property of equality explains that one value can replace another value in an expression or equation and the value will remain the same.
In other words if x + y = 7 and y = 5. Then I can rewrite the first statement as x + 5 = 7.
which can be solved to get x = 2. I just used the substitution property.
The first choice is the multiplicative identity property. Multiplying an expression by 1 gives the same result.
The second and third choices are wrong since 13 is not equal to 14 and neither is 13 equal to 6
The fourth choice is the additive identity property since adding zero to an expression gives the same result.
Good Luck!

Option A
<u>Answer:
</u>
The value of x in the equation 2(x - 3) + 5x = 5(2x + 6) is -12
<u>Solution:
</u>
From question given that
2(x - 3) + 5x = 5(2x + 6)
Open the brackets,
2x – 6 + 5x = 10x + 30
Rewrite the above equation,
2x + 5x – 6 = 10x + 30
On simplifying the above equation, we get
7x – 6 = 10x + 30
Now adding 6 on both sides,
7x – 6 + 6 =10x + 30 + 6
7x = 10x + 36
On subtracting 10x on both sides,
7x - 10x = 10x + 36 - 10x
-3x = 36
On dividing -3 on both sides,
x = -12
Hence on simplifying 2(x - 3) + 5x = 5(2x + 6) we get value of x is -12. Hence Option (A) is correct.
