Answer:
- c) Four times x over four equals four over four; Division Property of Equality
===========================
Given equation and steps to solve it:
- 4(x + 1) = 8
- 4x + 4 = 8
- 4x + 4 - 4 = 8 - 4
- 4x = 4
- 4x/4 = 4/4 <u>This is the missing step</u>
- x = 1
All steps given above including the missing one. As we can see, we divided both sides by 4, so the justification for this step is Division Property of Equality.
Hence, the correct choice is C.
I think you meant to put this problem into the chemistry category. This is the mathematics category.
Answer:
all real numbers
Step-by-step explanation:
the answer is all real numbers.
we know this since if you plug in any value for x we will get a real number.
hope this helps
