## knaub32 2 years ago When attempting to do his homework, Mark incorrectly uses the addition property of equality below. Which statement would correct Mark’s error? 1) 8 + x = 2 2) 8 – 8 + x = 2 3) x = 2 A. To balance the equation, Mark should also subtract 2 from the right side of the equation in step 2. B. To balance the equation, Mark should also subtract 2 from both sides of the equation in step 2. C. To balance the equation, Mark should also subtract 8 from the right side of the equation in step 2. D. To balance the equation, Mark should also add 8 to both sides of the equation in step 2

any ideas?

nope

Do you know what "the addition property of equality " is?

4. knaub32

nope, I don't understand math at all.

If the same number is added to equal numbers, the sums are equal. 8 + x = 2 this is an equation that says the two numbers 8 + x and 2 are equal, right?

6. knaub32

yeah I assume so

7. skullpatrol

The equals sign "=" is the basis of your assumption, correct?
