Question

Which property is included in the justification for the steps used to solve the equation ×+17=38

A. multiplication property od addition

B. subtraction property of equality

C. commutative property of multiplication

D. distributive property

Answer 1

The question is badly written.
By itself, x + 17 = 38 illustrates nothing.
If you do:
x + 17 - 17 = 38 - 17, then that would be using the subtraction property of equality.
So, C.

Answer 2

Answer: Option 'B' is correct.

Explanation:

Since we have given that

`x+17=38`

We need to find the value of 'x':

For which , we will subtract 17 from both the sides , and get

`x+17-17=38-17\\\\x=21`

Hence, we were using "Subtraction property of equality" which states that same number is deducted from both the sides of equality.

Thus, option 'B' is correct.
